The blind leading the blind.
"Therefore as by the offense of one (Adam) judgment came upon ALL MEN to condemnation; even so by the righteousness of one (Christ) THE FREE GIFT came upon ALL MEN unto justification of life" Romans 5:18.
There it is right in your face.
Rom. 5:18 can't apply to all men without exception.
What about the world that remains under God's condemnation and wrath John 3:18, 36?
So the ALL MEN of Rom. 5:18 applies exclusively to the Election of Grace Rom. 11:5 whether jew or gentile; Chosen of the Father in Union with Christ before the foundation of the world to be holy and without blame before Him in love; and to have forgiveness of sins Eph. 1:4-7.
So Justification of Life for these Elect of God has nothing to do with their own believing or anything else they do, but based solely upon the obedience of Christ on their behalf Rom. 5:19!
