Hi Ingledsva, remember when I told you I used to bar tend at a steak house in Muldoon, AK, and now you are willing to challenge and question the lofted commentators of the Scriptures, well, it appears that we have several things in common. Good for you, and I mean that in all sincerity.
Since you are willing to challenge the "experts" and those who are considered to be the authority in interpreting the Scriptures, I will open up a little to you.
When Paul stated that Adam was a figure or type of the coming one, he did not want the comparison to be through THE OFFENSE, but rather, the FREE GIFT. Both Adam and Messiah gave mankind a gift, and that IS the comparison, the type or figure which Paul spoke about. Adam's gift was condemnation and death, and Messiah's was righteousness and life. Adam's gift was the result of ONE transgression (offense), and Messiah's gift was the result of MANY transgressions (offenses) (see v16). So again, you cannot make the comparison through the offense, but rather through the free gift that they both gave.
ALL traditional christian commentators, theologians, college professors, and teachers are caught with their pants down at their ankles. They are clueless in understanding how Adam was a type or figure of the coming one, and the correct translation of the first sentence of Romans 5:15, should be as follows:
"But not through the offense, rather the free gift."
Do you see it? Paul had just stated Adam was a type or figure of the coming One, so his next statement explains how Adam was a type or figure of the coming One. And it was not through the offense, rather it was through the free gift that they both gave to mankind. So you are correct, there is no comparison between the Messiah and Adam if you look at the offense/transgression, but if you look at the free gift that they both gave, there is a comparison.
I hope you will join me in this understanding of what Paul meant when he said that Adam is a type or figure of the coming One. KB
