“For I have come down from heaven, not to do My own will, but the will of Him who sent Me. 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 6:38-39)
I would say that Jesus is expressing here that He will not fail in His mission to redeem the world. He Himself will not lose anyone, while we may still choose contrary to His will. We can be lost, as we have the free will to do so, though it will not be because of Jesus. Jesus will not lose anyone.
In John it says “no one shall snatch them out of my hand.” This is true, as no person has the power to separate us from God. This again does not mean that we cannot choose to remove ourselves from His hand.
It also says in John “My sheep hear my voice, and I know them, and they follow me;” Indeed the sheep follow, but we see in Matt. 18:12-13 that some do go astray, and can be brought back “if he finds them”
“What do you think? If a man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go in search of the one that went astray? And if he finds it, truly, I say to you, he rejoices over it more than over the ninety-nine that never went astray.”
