Matthew Henry Commentary
John 6:36-37
He understands that those standing before Him and listening to the very words of life do not have this kind of faith. Thus, they have no commitment. However, verse 37 makes a first encouraging step, "All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out." He is speaking of those whom the Father would give Him as disciples from that time forward, including us, and all these can have this faith and commitment. The Father Himself elects, chooses, each one, giving each the necessary gift of faith, as Ephesians 2:8 shows.

John 6:37:40
“All that the Father gives Me shall come to Me, and the one who comes to Me I will certainly not cast out. 38 “For I have come down from heaven, not to do My own will, but the will of Him who sent Me. 39 “And this is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. 40 “For this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day." (
John 6:37-40).
In verse 37, Jesus says, “All that the Father gives Me shall come to Me, and the one who comes to Me I will certainly not cast out." It is clear that the Father gives to the Son those who believe and that Jesus says he will not cast them out.
In verse 38 Jesus says, “For I have come down from heaven, not to do My own will, but the will of Him who sent Me." Jesus tells us he is here to do the will of the Father. What is the will of the Father?
John 6:39-40, “And
this is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. 40 “For
this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day."
We can easily draw the conclusion that the will of the Father is that
all who were given to the Son (v. 39) will not be lost and will be raised on the last day, but the common objection is that the will of the Father is not always accomplished. In other words, it is the will of the Father that none be lost; but since his will is not always accomplished, there will be people who were saved but then became lost. This might seem a possible interpretation; but when we look at the next verse, we see it doesn't work. In verse 40, Jesus continues to tell us what the will of the Father is by saying that everyone who beholds the Son and believes in him will have eternal life and that Jesus would raise him up on the last day.
Various versions translate verse 40 differently. The NIV says, "shall have eternal life." The KJV, NKJV, NRSV say, "may have everlasting life." The RSV, ASV, ESV, GNT, ISV, NLT say, "should have eternal life;" NASB95, "will have eternal life." So, is eternal life something we
may have when we believe or
actually have when we believe? In other words, are we saved when we believe or not? It cannot be that we "may" have eternal life (be saved) if we believe because believing is what justifies us (
Rom. 5:1); only the saved are justified. Furthermore, upon believing, we have eternal life; and we can know we have it as
1 John 5:13 says, "These things I have written to you who believe in the name of the Son of God, in order that you may know that you have eternal life." To settle the issue,
John 6:47 says, “Truly, truly, I say to you, he who believes has eternal life." So, we can conclude that there is no conditional eternal life upon believing but that we receive salvation and eternal life when we believe, which is why it says all who behold the Son and believe will have eternal life.
If verse 39 can be interpreted to say that the will of the Father can fail and some perish, then verse 40 must likewise be interpreted to say that the will of the Father fails in that those who believe on Jesus won't be saved and don't have eternal life. This cannot be! Otherwise, no one who believes in Christ can be sure he or she presently has eternal life--which is in contradiction to
1 John 5:13 which says we
can know!
Therefore, both 39 and 40 must be interpreted in the same manner; namely, that the will of the Father is actually accomplished in that all who belong to the Son will not perish,
and all who believe on the Son will have eternal life. Again, if all who belong to the Son
might perish, then likewise all who believe on the Son
might not be saved; that is, they might not possess eternal life if they believe in Christ! If that is the case, then we aren't justified by faith (
Rom. 5:1).
Furthermore, versus 39 and 40 tells us that Jesus will raise them up on the last day. The one group of people who are raised on the last day are those who have been given by the Father to the Son (v. 37), who have believed on the Son (v. 40), who have eternal life (v. 40), and cannot be lost.
