What does the Bible say about man's nature and sin?

The Scriptures declare that all have sinned and fall short of the glory of God (Romans 3:23). This sinful nature is a direct consequence of the Fall, where Adam disobeyed God, leading to the spiritual death of all his descendants. Romans 3:10-12 states, 'There is none righteous, no, not one; there is none who understands; there is none who seeks after God.' This highlights humanity's inherent opposition to the true and living God, revealing our need for regeneration and spiritual life. With this fallen state, man's inclination is to worship something other than God, often creating idols in his own likeness (Romans 1:25).
