The disciples' persistent failure to grasp our Lord's teaching must have 
        been a great source of trial and frustration for Him. Despite His warnings 
        about His coming sufferings, the disciples failed to comprehend this; 
        perhaps partly due to Jesus Himself fluctuating between talking of his 
        death in both literal and then figurative terms. In His time of greatest 
        need of encouragement He found them sadly lacking in any real degree of 
        spirituality beyond a fanatic allegiance to Him. And yet He graciously 
        thanked them for continuing with Him in His temptations, even though they 
        fell asleep (Lk. 22:28). We can under-estimate how sensitive He is to 
        our feeble spirituality, and how even the basic will to be loyal, no matter 
        how much we fail in practice, means so much to Him. Yet their lack of 
        comprehension must have been especially tragic, since one of the reasons 
        for the gift of the disciples was to help Jesus through the pain of His 
        ministry, and this was to culminate in the cross. After the Jews' first 
        council of war against Christ, He prayed for strength and was answered 
        by being given the twelve (Lk. 6:11-13). No doubt He found the soldiers' 
        mocking him because of Peter's weeping and weakness (Lk. 22:62,63) especially 
        hard to take (Mk. 14:69 implies the courtyard conversation was also about 
        the disciples). Likewise their angry “Carest thou not that we perish?” 
        (Mk. 4:38). His whole life and death were because He did so care 
        that they would not perish (Jn. 3:16). It’s so reminiscent of a child’s 
        total, if temporary, misunderstanding and lack of appreciation of the 
        parent’s love and self-sacrifice. 
      The Lord's goodbye address in Jn. 14-16 has many connections with those 
        of Moses and Joshua, in which they expressed fear that after their death 
        there would be a mass falling away within Israel, and their guise of spirituality 
        would give way due to their lack of a real word-based faith. This further 
        indicates the weakness of the disciples. Our Lord's speech was shot through 
        with doubt of the twelve and recognition of the weakness of the disciples, 
        which needs tabulating to show its full force:
            On their own admission in the Gospel records, the understanding of the 
        disciples was pitiful. Not only did they not really listen to the Lord’s 
        words, the words of the Only Begotten Son of God, but they retained many 
        misconceptions from the world around them which did not accept Him. Here 
        are a few brief examples:
      
        - They failed to see after two miracles relating to bread, that literal 
          bread was not so significant to the Lord (Mk. 8:19-21)
        - Twice they wanted to turn away those who wished to come to Jesus, 
          and whom He wished to accept (Mt. 14:15; 15:23). As with the two miracles 
          of bread, the second incident was giving them the opportunity to learn 
          the lesson from the first incident- and yet they failed. Likewise they 
          “forbad” John’s disciples just as they wrongly “forbad” the little children 
          to come to Him (Lk. 9:50).
        - When we read that “there cometh one from the ruler of the synagogue’s 
          house, saying to him, Thy daughter is dead, trouble not the Master” 
          (Lk. 8:49), we naturally ask: who was this “one” who came with 
          this message? In the Gospels, it is often the disciples who term Jesus 
          “the Master”. The implication is that it was they who thought that Jesus 
          wouldn’t have the power to raise the dead, perhaps connecting with their 
          own studied lack of faith in His resurrection later.
        - They tried to do miracles without even praying about it (Mk. 9:29)
        - They knew not what manner of spirit the Lord had given them (Lk. 
          9:55)
        - Jn. 1:38 records how the disciples were asked: “What seek ye?”, and 
          they reply: “Where dwellest thou?”. Remember that this is John, one 
          of them, recording their response. It’s as if he’s pointing out how 
          inappropriate was their response to Jesus; rather like the record of 
          Peter wanting to build a tent for Jesus, Moses and Elijah so they stay 
          a bit longer. They had responded inappropriately- and yet they 
          urged their hearers and readers to respond appropriately.
        - When the Lord taught them about His death, they always seem to have 
          started arguing amongst themselves; the tremendous significance of what 
          He was saying was evidently lost on them (Mk. 9:31-34; 10:34-38).
        - They were amazed that it was hard for rich people to enter the Kingdom 
          (Mk. 10:24)
        - Mk. 11:14,21,22 imply that Peter was amazed that something the Lord 
          had predicted about the fig tree had actually come true.
        - After their failure of faith on the lake, they describe themselves 
          as the men who were in the ship- as if they felt unworthy to call themselves 
          disciples of the Lord (Mt. 14:33). Yet remember that these records were 
          written or spoken by them in their preaching of the Gospel, 
          and recounting their own experiences. 
        - “Your unbelief” (Mt. 17:20). “Ye of little faith” (Lk. 12:22,28); 
          they had “no faith” (Mk. 4:40). “Where is your faith?” (Lk. 8:25). They 
          asked for their faith to be increased (Lk. 17:5). Luke records that 
          the Centurion had more faith than the disciples (Lk. 7:9). 
        - The disciples were told to sell what they had (Lk. 12:22,32,33); 
          but it seems they kept their fishing business. After having asked them 
          this, the Lord again had to speak to them about forsaking all that they 
          had (Lk. 14:33). Their claim to have left literally all and followed 
          Him (Lk. 18:28) appears somewhat exaggerated. To follow Him meant taking 
          up a cross (Lk. 14:27).
        - Lk. 10:20 implies that their elation at being able to pull off miracles 
          was wrong, or at best immature; rather should they have rejoiced that 
          their names were written in Heaven.
        - Mt. 19:9.10 records how they thought that the Lord’s policy of no 
          divorce except for “fornication” meant that marriage was “not good”. 
          And yet the Genesis record clearly states that it was “not good” for 
          a man to be unmarried. Matthew in his own [over-ruled] word choice seems 
          to be commenting how they were out of step with the spirit of Genesis.
        - They so often feared (Lk. 8:25; 9:34,45; Mk. 4:40; 6:50; 10:32); 
          despite the Lord repeatedly telling them not to be afraid (Lk. 12:4,32; 
          Jn. 14:27).
        - They were preaching the words of the Gospels in response to their 
          Lord’s command to go preach. Yet Jn. 4:35,38 records them recognizing 
          that they didn’t appreciate how great the harvest was, and indeed the 
          harvest was spoilt because of the weakness of the disciples.
        - Their records bring out their own fickleness. After having been awed 
          by the Lord’s stilling of the storm, they are soon almost mocking Him 
          for asking who had touched Him, when hundreds of the jostling crowd 
          had touched Him (Lk. 8:25 cp. 45).
        - They ask the Lord to send the multitude away (Mk. 6:36), whereas 
          Jesus had taught by word and example, that whoever came to Him He would 
          not turn away (Jn. 6:37), and had just shown that He did not ‘send away’ 
          the demons from the sick man, because the man had asked for them not 
          to be sent [far] away (Mk. 5:10).
        - Jn. 6:15-17 implies they got tired of waiting for the Lord Jesus 
          to return from prayer, and so they pushed off home to Capernaum, leaving 
          Him alone. Yet by grace He came after them on the lake, to their salvation.
        -They interrupted a parable, clearly not understanding it (Lk. 19:25). 
          Yet the Lord said that His parables were only not understood by the 
          unbelieving Jewish world. 
        - Even much of the spirituality and understanding which they appeared 
          to have was in fact only of a surface level. He complains that none 
          of them ask Him “Whither goest thou?” (Jn. 16;5)- even though they had 
          just asked Him those very words (Jn. 13:36). They said the words, but 
          not from a heart of true understanding. It's an epitome of the weakness 
          of the disciples.
               - It was the disciples 
                who called Jesus ‘Master’. When we read that “there cometh one 
                from the ruler of the synagogue’s house, saying to him, Thy daughter 
                is dead: trouble not the Master” (Lk. 8:49), we are presumably 
                intended by Luke to understand this messenger as actually a disciple. 
                Again, the record is emphasizing how limited was the disciples’ 
                vision and faith in Jesus. 
               - The Lord had to tell 
                the disciples after the resurrection to “Break your fast” (Jn. 
                21:12 RV). Despite the Lord having appeared to them as recorded 
                in John 20, they were fasting for the dead. No wonder the Lord 
                urged them to break that fast. But the point is made, by John 
                himself, as to how terribly slow they were to believe in His resurrection.
               - Luke records that the 
                Lord sent out 72 preachers (Lk. 10:1)(1). The Jews 
                understood that there were 72 nations in the world, based on the 
                LXX of Gen. 10. Surely Luke’s point is that they went only to 
                the Jews, thus highlighting the gap between the disciples’ understanding 
                at the time, and the Lord’s further reaching intention of a mission 
                to the Gentiles.
               - When you think about 
                it, the record in Mt. 19:9 is not at all to the disciples’ credit. 
                They state that if you can’t divorce, it’s better not to marry. 
                But Matthew records the Lord explaining that the standard for 
                God’s people is the one man: one woman for life which we find 
                in Genesis. And yet Matthew also records how the disciples totally 
                failed to appreciate that at the time, by making the comment that 
                marriage was a bad idea if there could be no divorce. 
               - It’s easy to 
                misinterpret Jn. 16:16: “A little while and ye behold me no more… 
                ye shall see me”. Elsewhere in John, beholding or seeing the Son 
                doesn’t refer to physically seeing Him, but rather to understanding 
                and believing in Him (Jn. 1:14,29,36,50; 6:40; 12:21; 14:9,19; 
                17:24 etc.). The Lord surely meant: ‘Soon, you will no longer 
                see / understand / believe me… but, in the end, you will 
                understand / believe in me’. And John, the author or speaker of 
                this Gospel record, was one of those being referred to. So he, 
                and all the disciples, would’ve been appealing to people to see 
                / understand / believe in Jesus, whilst openly telling them that 
                they themselves had once lost that understanding / belief which 
                they once had, even though they regained it later. 
              - The crowds that 
                followed the Lord didn’t understand His parables; in fact, 
                He spoke in parables so that they wouldn’t understand, as 
                He intended His teaching only to be grasped by the disciples (Mk. 
                7:17,18). Therefore, in that very context, it is significant to 
                read of the Lord’s frustration and disappointment when the 
                disciples likewise didn’t understand the parables. And the 
                record goes on to show that in fact it was a regular occurrence, 
                that they like the crowds didn’t understand the parables, 
                and the Lord had to explain to them later. So the disciples, contrary 
                to the Lord’s high hopes of them, were no better than the 
                crowds. They too ‘didn’t get it’; and Mark’s 
                [i.e. Peter’s] record of the Gospel therefore brings out 
                the point that they too, the ones now preaching to the crowds, 
                only got the understanding they did of the Lord by an undeserved 
                grace. This is the kind of humility we need in our teaching of 
                others, especially when it involves correcting their lack of understanding 
                on a point. 
               
                 It was popular in the first century for religions to ‘re-publish’ 
                the teachings of their leader in story form, along with some pious 
                biography of the founder and his initial followers. To this was 
                added a condensation of the teacher’s sayings into some fixed 
                code that was binding upon the religion(2). The Gospels 
                are in that sense in a similar genre- but they are radically different, 
                because they show the initial followers to be so human, 
                and hardly pious; and they present no fixed moral code distilled 
                from the Lord’s teachings. Rather they present simply a Man, a 
                personality, which is to be the pattern for His followers. 
         
               
                Both Matthew and Mark record how the people mocked Jesus over 
                His comment that if the temple were destroyed, He would rebuild 
                it in three days (Mt. 27:40; Mk. 15:29). This had also been an 
                issue at the Lord's trial (Mt. 26:60). Yet John records that when 
                the Lord actually said those words, the disciples didn't believe 
                those words and actually forgot them until the time of the resurrection 
                (Jn. 2:22). The implications of that are tragic. The Lord's critics 
                remembered His words more than His disciples did. And as He stood 
                there in the awful loneliness of His trial, and hung there in 
                the desolation of crucifixion, and heard those taunts based around 
                His earlier words... He would've known that His own men had forgotten 
                those words and likewise disbelieved them. No wonder after the 
                resurrection He raised the matter with them. My point in this 
                context is that John's comment in Jn. 2:22 about the fact the 
                disciples forgot those words until after the resurrection... is 
                actually a conscious recognition by the disciples of their own 
                tragic weakness in understanding and support of their Lord. And 
                it is within their own preaching of the Gospel that they make 
                this point.
