What does the Bible say about the state of mankind?

According to Romans 3:23, 'For all have sinned and come short of the glory of God.' This declaration indicates the universal condition of humanity; everyone, without exception, is in a state of sinfulness and is unable to attain the perfection required by God. The verses leading up to this highlight mankind's utter depravity, affirming that there is none righteous, no, not one (Romans 3:10). This reinforces the notion that without divine intervention, every person stands hopeless before God, necessitating God's grace and mercy for any hope of justification.
