Is God’s plan on track? Were we created to be sinners?

DL:

Paul took note of this logic in Romans 9:18-20:

[b]"Therefore God has mercy on whom He wants to have mercy, and He hardens whom He wants to harden.

One of you will say to me, “Then why does God still blame us? For who can resist His will?”

But who are you, O man, to talk back to God? Shall what is formed say to Him who formed it, “Why have you made me like this?”[/b]
