The Apostle Paul indeed employed stark contrasts to underscore his teachings on salvation and eternal life. In Romans 5:18, he juxtaposed the consequences of one trespass with the outcomes of one act of righteousness, highlighting the parallel between condemnation for all through sin and justification leading to life through Christ's righteousness.

Expanding on this theme, Paul dedicated two chapters, 6 and 7, to explain that believers are no longer bound by the law but are now united with Jesus Christ. He emphasizes that believers have been freed from condemnation, as seen in Romans 8:1: "There is no condemnation for those who are in Christ Jesus."

Consequently, Paul draws a clear distinction between those who are in Christ, saved from condemnation, and those who are not, still subject to condemnation. Through various contrasts and illustrations, Paul elucidates the profound difference between the saved and the lost, emphasizing the pivotal role of being in Christ for salvation and freedom from condemnation.
