But I'm still not sure that ignorance of sin will not condemn us? What do you think?
I really look at this very differently from you.
I don't think that ignorance of knowledge of sin is what is at issue. I don't think even the commission of sin is the issue. The sinner sins, and the child of God does righteousness.
Some of the thoughts out there are . . .
A child of God sins, and it just shows they aren't a child of God, because no child of God sins.
A child of God sins, and they stop being a child of God.
A child of God sins, and they have a way to make it right with God, and they do, or they don't.
Or is there another option?
You've pointed to something done that you recognize was wrong, and perceive God did a miracle with you, in that even though there was sin, yet there was no separation.
You've pointed to God's foreknowledge as the reason. That He knew you would be righteous at the end, so He did not count the sin, and did not separate from you.
I suggest there is a different reason. I think this does begin with foreknowledge . . .
Romans 8
29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
31 What shall we then say to these things? If God be for us, who can be against us?
32 He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
33 Who shall lay any thing to the charge of God's elect? It is God that justifieth.
34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
Having foreknown us, He predestinated us, set limits in advance, to be made just like Jesus. So He also called, and justified, and glorified.
God gives us Christ, and everything else. None can charge or condemn us, because God justifies us, because Christ died and rose again, and died and rose in Him.
I think that God has justified us away from sin, that this is to be born a new creation, not in the line of Adam, not from the man of earth, earthy, but from the man of heaven, heavenly.
Much love!
