How does the Bible contradict the sinner? You think you are basically good but the Bible says you are a bad person (Romans 3:10-19, 1 Corinthians 6:9-10). You think you are saved by whatever good works you may possess but the Bible says you are not saved by your good works (Ephesians 2:8-10, Titus 3:5). Some people may want a salvation that will allow them to sin all they want but the Bible says that true salvation changes your life (Titus 2:11-14). Some people may want health, wealth and prosperity all the time but the Bible says no such garbage. The Bible does not cater to the sinful wants of man because it goes against them.

Romans 7:22 in the same passage Paul complains about his struggle against sin also has him saying, "For I delight in the law of God after the inward man:".
