I can't speak for Kolo, but he is right -- God is indifferent to sin. What we do can neither please nor displease Him. If we could, He would be subject to pleasure, and passion.
God is simply offering us to be restored to our original state -- because He loves us.
And by the way, the Old Testament, with floods and the stuff, also says that God repents (Gen 6:6)...that God changes His minds! Imagine that! That God, the Almighty Sovereign Creator of everything and all, the all-knowing and all-seeing Spirit Who is everywhere and Who transcends everything and all, makes a mistake, regrets, and changes His mind!
It's not that it didn't happen. It's that we don't interpret it correctly. Even Jesus redefined the OT "eye for an eye," (Mat 5:38-39) showing that the people whom God chose to reveal His truth not onyl left Him on many occasions, but also maybe interpreted His revelation somewhat oddly, and corrupted the pristine Covenant He made with them (Heb 8:7).
Amazing. We must be reading different Bibles altogether.
