What does the Bible say about sin and evil?

The Bible categorizes sin into three types: transgression, sin, and iniquity. Transgression refers to rebellion against God's law, which includes breaking the commandments and refusing to obey God's commands. Sin, more broadly, represents any offense against God, as well as against one's neighbor. Iniquity, on the other hand, signifies a state of being that reflects man's inherent perverse nature, illustrating that all have sinned and fall short of the glory of God. Together, these terms paint a comprehensive picture of humanity's moral condition in relation to a holy God, showcasing the depth of our need for redemption.
