What does the Bible say about sin and our nature?

According to the Bible, particularly in Romans 3:23, all have sinned and fall short of the glory of God. This sinful nature predisposes us to self-worship, as illustrated by King Herod's actions. Herod exemplifies the natural inclination to prioritize one's own desires over God's commands, showcasing how our depravity leads us to think we can choose our own good and evil, thus making ourselves as gods. Such rebellion reveals a desperate need for a Savior to reconcile us to God, as our sin is not merely external but rooted in our hearts.
