And this is the will of him that sent me, that every one which {l} seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.

(l) Seeing and believing are joined together: for there is another type of seeing which is general, which the demons have, for they see: but here he speaks about that type of seeing which properly belongs to the elect.

People's New Testament

6:39,40 This is the Father's will. The Father's will is that every one who sees the Son and believes upon him, thus coming to, following and abiding in him, shall have eternal life, and that in the resurrection day Christ shall raise him from the grave. These verses show, (1) That there is not any secret decree of election. The will of the Father applies to every one who believes upon the Son. (2) The condition of eternal life is a faith that leads to and appropriates Christ; that makes him the Lord of the soul. (3) Christ hath brought to light immortality. He is the resurrection and the life (Joh 11:25).

Wesley's Notes

6:40 Here is the sum of the three foregoing verse s. This is the will of him that sent me - This is the whole of what I have said: this is the eternal, unchangeable will of God. Every one who truly believeth, shall have everlasting life. Every one that seeth and believeth - The Jews saw, and yet believed not. And I will raise him up - As this is the will of him that sent me, I will perform it effectually.

Jamieson-Fausset-Brown Bible Commentary

40. And this-in the second place.

is the will of Him that sent Me, that every one which seeth the Son and believeth on Him-seeing the Son believeth on Him.

may have everlasting life, and I will raise him up at the last day-This is the human side of the same thing as in the foregoing verse, and answering to "Him that cometh unto Me I will in no wise cast out"; that is, I have it expressly in charge that everyone that so "beholdeth" (so vieweth) the Son as to believe on Him shall have everlasting life; and, that none of Him be lost, "I will raise him up at the last day." (See on [1793]Joh 6:54).

Matthew Henry's Concise Commentary

6:36-46 The discovery of their guilt, danger, and remedy, by the teaching of the Holy Spirit, makes men willing and glad to come, and to give up every thing which hinders applying to him for salvation. The Father's will is, that not one of those who were given to the Son, should be rejected or lost by him. No one will come, till Divine grace has subdued, and in part changed his heart; therefore no one who comes will ever be cast out. The gospel finds none willing to be saved in the humbling, holy manner, made known therein; but God draws with his word and the Holy Ghost; and man's duty is to hear and learn; that is to say, to receive the grace offered, and consent to the promise. None had seen the Father but his beloved Son; and the Jews must expect to be taught by his inward power upon their minds, and by his word, and the ministers whom he sent among them.
