If the world is sinful, how can sin be "exposed"?
That no one could fully keep the law to GODS expectations.
So god introduced a bunch of impossible-to-follow laws, then told no one about the punch line until some 1,000 years or so later.
I'm not even going to try to imagine how many generations that amounts to.
Man fall was a huge one. Deceived into believing we could become like GOD. Didn't happen, not going to happen.
Yadda, yadda, yadda, preaching.
We were already made in His image and likeness to begin with, but GOD is GOD. There is none other.
So man looks like god? Why does god have man-nipples? What does god uses his testicles for?
His plan for Salvation was already set into motion from the beginning. It is through Jesus Christ this Salvation came by the grace of GOD because He loves us. He always has.
So why wait 1,000 years to impliment the plan? Why not do it right away at the fall, or at least by the time of the flood? With a 1,000 years waiting time, it's no wonder that god's chosen people thought the Jesus plan was a bunch of hokey...
