What does the Bible say about being unclean before God?

The concept of being unclean before God, as illustrated in Leviticus 15, refers to a state of sinfulness that separates us from God's holiness. The woman in Mark 5:23-34 represents all of humanity in our unclean state, having offended God through sin. Just as she was required to make sin and burnt offerings for atonement, we too need reconciliation with God, which highlights our desperate need for grace. God's law reveals our guilt, making it evident that we are unclean and in need of cleansing through Christ.
