You will probably find well-meaning Christians trying to reassure this poor fellow, who, had he been taught the Gospel that is entirely of Grace, would understand that his eternal destiny does not hinge on the integrity of his decision, but entirely on God's decision.
Our first post talks about the fact that "God is love". And ones claim He can't have our love unless we have free will to freely choose to love Him. But if I am in sin, how well can my free will have the right character to make a truly loving choice? And if I am equal truly with other sinful people, how can I somehow be superior to others so I choose Jesus while others do not?
And if God is love, why would He leave me on my own to make a decision which depends on my ability . . . in sin and slavery to Satan (Hebrews 2:14-15) . . . to make a choice in my sin-degraded will's ability?
I would need for God's grace to effect me and share His love's ability with me. By the way, I see we do make a choice, yes, but in sharing with God making our character capable of being humbly submissive with Him in us >
"for it is God who works in you both to will and to do for His good pleasure." (Philippians 2:13)
Plus, of course, we have how Jesus already has done on the cross all we could not do for ourselves, and now one needs for God also to do inside the person what he or she with sinful character could not get oneself to do.
So it is practical, then, how God's action of grace alone is able to cause what is truly enough for Him, in us. Or, we could glorify and worship our own free wills, couldn't we?
And so, God who is love has brought us out of our sin's inability and stupidity and stubbornness which guaranteed we would never on our own change to trust in Jesus.
But God in His love's almighty ability changed us to be humble to choose Jesus. We became humble, only because of sharing with Jesus who alone is truly humble . . . enough to please God with a choice which is truly humble
Because He is love who did not leave us on our own . . . like the loving parent who does not leave a foolish child at the mercy of the child's ability to make choices.
