Comprehension is subjective. Again, I refer you back to Matthew 5. Law done away with? Your Messiah said "18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled". Obviously "all" hasn't been fulfilled yet cuz Heaven and earth are still here. Trinitarian interpretations of such things as "the fall" and "original sin" seem to fog one's perception.
In Christ, we have a new creation, all things are being made new, when He returns it will be complete
