Jn. 6:36 But I said unto you, That ye also have seen me, and believe not. 37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. 38 For I came down from heaven, not to do mine own will, but the will of him that sent me. 39 And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. 40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day. John 6:36-40 is a distinct unit complete in itself. For example notice verse 36 introduces "ye...have seen me, and believe not" while verse 40 closes with the reverse "every one which seeth..and believeth." The distinction is not in regard to seeing but in regard to believing. So in verse 36 we have introduced a negative response in regard to believing in Christ while verse 40 has done a complete reversal by closing this passage with a positive response in believing in Christ. Verses 37-39 provide the transition from the negative to the positive, and is therefore explanatory to what brought about this transition from unbelief to belief in Christ. Hence, "cometh" in verses 37-39 means to come to Christ in faith. Secondly, in verse 37 "shall come' is future tense from the present tense "giveth" showing the cause and effect relationship between giving and coming. They don't come in order to be given by the Father to the Son, but they come because they have been given by the Father to the son. If this is doubted then, Christ removes all doubts in verse 39 by using the perfect tense "given" in regard to the will of the Father concerning the incarnation event. That is, Christ's coming from heaven to earth was to in order to fulfill the will of His Father which was to secure those already having been given to him. Hence, the act of giving preceded the incarnation and was part of the cause for Christ leaving heaven and coming to earth. Thirdly, none of those given the Father, for which Christ came to earth to secure their salvation will be lost. Therefore, this previous act of being given by the Father had salvational intent that was effectual. Fourthly, the "will" of the Father here is not his revealed will to us or for us, but expressive and explanatory for Christ coming to earth to secure "all" the Father had already "given" him so that not one is lost. Fifthly, the effectual nature of that will is summarized by the words "but should raise it up again at the last day." God will raise lost and saved up at the last day. However, this statement is made to reaffirm that "of all" those having been given by the Father to the Son that He would lose nothing. Hence, this conclusive statement is designed to characterize ALL who have been given and NNE ELSE! Sixthly, that same identifying statement closes verses 40, 44, and 54 proving that Christ is referring to the very same "all" or those having been given to him by the Father for which he came into the world to secure the will of the Father in regard to their effectual salvation. Seventhly, therefore, the "whosoever will" in verse 40, and the "he" that is drawn in verse 44 and the "whoso" of verse 54 are "OF ALL" those previously given to the Son by the Father before the Son ever came into the world. Finally, the transition from those who saw and believed not in verse 36 to those who see and believe in verse 40 is due to the fact that those in verse 40 are "of all" those the Father had given to His Son, while those in verse 36 are not "of all" those who had been given to his Son, because ALL that the Father gives to the Son "SHALL come" to him and these did not.
