What does the Bible say about being unclean?

The term 'unclean' in the Bible signifies a state of moral and spiritual impurity that all humans are born into due to the fall of Adam. This condition renders us incapable of achieving holiness or righteousness on our own. Scriptures like Mark 5:2-3 highlight the example of a man possessed by unclean spirits, illustrating the natural state of all mankind who dwell in spiritual tombs, devoid of life and separated from God. It's only through the redemptive work of Christ that individuals can transcend their unclean state and be made whole.
