What does the Bible say about our nature in Adam?

The scripture outlines that by nature, we are all corrupted by sin through Adam. Romans 5:12 states that sin entered the world through one man, and death through sin, thus death spread to all men because all sinned. This reflects a universal depravity where every individual, like the man possessed by a legion of devils, is capable of sinking into sin's depths. Ephesians 2:1-3 affirms that we were dead in our trespasses and sins, led by the spirit of disobedience, illustrating that without God's grace, we are all lost and in need of redemption.
