Jesus declared: "And this is the WILL OF HIM who sent me, that I should LOSE NOTHING of all that he has given me, but raise it up on the last day. For this is the WILL of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.” (John 6:39, 40)
Jesus will lose nothing of all the Father has given him. How many people will Jesus lose of all those the Father has given Him? None of them, he says. And He further promises they will be among those in the resurrection of the righteous at the last day. Jesus declares this is GOD'S WILL and unless one thinks they can thwart God's will (an impossible supposition) or that God can reverse His promise, then the only biblical conclusion we can reach is that Christ graciously preserves all whom He saves. It would be presumptuous to say God can go against his own promise and will. In fact, to believe that one can lose his/her salvation is to say Jesus is not enough ... which is an attempt to strike or cut down the very root of the very gospel itself. Those who think they can add to Christ's work are in danger of the heresy Paul describes in Gal 3:3: "Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh?" If you think grace is not enough but you must maintain or contribute toward your just standing before God, then you have not understood the gospel at its very heart. But the good news of the gospel is that Jesus did it. He provided EVERYTHING we need for salvation including a new heart which believes and perseveres to the end.
