That is correct.
Now let's see what that verse really says...
John 6:39
“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.”
That lines up perfectly with the rest of Scripture that tells us that God does not want anyone to go to Hell. This does not mean that no one is going there. This does not mean that there is some pre-registered group that is exempt from needing to make a choice.
2 Peter 3:9
“The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.”
Do you see that? They need to "come to repentance".
John 17:12
“While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.”
That is a simple statement of fact. This does not say that it had to happen that way. As a matter of fact, it even tells us that one was lost. They all made their choice, and so must we.
Have you made your choice?
Are you suggesting that God loves all of mankind and that it is his will that they would all have the inheritance of heaven?
Dan 4:35 - And all the inhabitants of earth are reputed as nothing, and he doeth according to his will in the army of heaven, and among the inhabitants of the earth, and NONE can stay his hand, or say unto him, What doest thou? If God wanted to take all of mankind to heaven, nothing could stop him, especially mankind.
Eph 1:5 - Having predestinated us unto the adoption of children by Jesus Christ to himself, ACCORDING TO THE GOOD PLEASURE OF HIS WILL.
Isaiah 55:11 - So shall my word be that goeth forth out of my mouth, it shall not return unto me void, BUT IT SHALL ACCOMPLISH THAT WHICH I PLEASE, and it shall prosper in the thing whereunto I sent it.
Rom 8:28 - And we know that all things work together for good to them that love God, TO THEM WHO ARE THE CALLED ACCORDING TO HIS PURPOSE.
Eph 1:11 - In whom we also have obtained an inheritance, being PREDESTINATED ACCORDING TO THE PURPOSE OF HIM WHO WORKETH ALL THINGS AFTER THE COUNSEL OF HIS OWN WILL
2 Tim 1:9 - Who hath saved us, and called us with an holy calling, not according to our works, but ACCORDING TO HIS OWN PURPOSE AND GRACE, which was given us in Christ Jesus before the world began.
God does not offer or plan. God Purposes his will and does it.
Most of the choosing in the scriptures is God choosing, and not mankind choosing. God gave mankind the freedom to choose out the way he wanted to live his life here on earth, but God did the choosing for mankind's eternal inheritance. Give me a scripture where man chooses eternal life.
2 Pet 3:9 - We find in 2 Pet 1:1 who Peter is speaking to in 2 Pet 3:9, and it is to them that have obtained like precious faith with us. Peter also includes himself in his warning to them by using the word "usward". Peter is instructing them about God's promise that he is not willing that any of them should ( "perish=death=separation") separate themselves from his fellowship by committing a sin, and when they do, to repent to regain their fellowship back.
The unregenerate person will not repent of breaking a spiritual law from a spiritual God, that he cannot discern, and thinks them to be foolishness (1 Cor 2:14).
