I came across these verses while studying the Bread of Life passages.
(John 6:39) - "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."
(John 6:40) - "For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day."
(John 6:44) - "No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day."
It is both those who are called by the Father and those who believe in Christ who are raised up on the last day. The two criteria are synonomous. God choice of us is manifested in our belief in Christ. Christ could have easily said to the multitude - 'I choose you and you and you' - but Scripture says:
(John 6:64-65) - "But there are some of you who do not believe. For this reason I have said to you, that no one can come to Me unless it has been granted him from the Father."
But Christ's instructions from the Father was to preach the gospel. Why? Because the gospel is the means by which people believe in Christ - and from John 6:28, our belief is a work of God.
(John 6:28-29) – “Therefore they said to Him, "What shall we do, so that we may work the works of God?" Jesus answered and said to them, "This is the work of God, that you believe in Him whom He has sent."
(Rom. 1:16) – “For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes,...”
And by the way - Christ loses no one that the Father sends Him. We will be raised up on to last day.
The work of God is our belief in Christ.
The power of God is the gospel that is preached by which we believe.
The will of God is that Christ loses none that God sends to Him.
The grace of God is that any of this happens at all.
(Eph. 2:8) – “For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;”
