There are two places we typically run when we see our sin: we run and hide under our religion or morality, or we run in outright rebellion like the prodigal son. Both responses take us further from freedom, further from God's love. Repentance is the confession of the specific ways I have offended God, turning away from the sin and toward God for forgiveness. God doesn't ask us to confess so we will feel guilty, but so we will find freedom to and come back to him.
