Conditional grace is not grace. The human experience of grace is so much larger than what you describe.
Whereas, while we were still sinners (enemies of God), Christ died for us. He laid His life down for us. He left everything He had in heaven to save those He loved. At every point, we were undeserving enemies. If we repent and trust Him, we still keep turning on Him and failing. Yet, nobody can snatch us out of His hand.
That’s grace upon grace that God lavishes upon those who believe in Jesus Christ.
