Create in me a clean heart, O God, and renew a right, persevering, and steadfast spirit within me. ( Pslm. 51:10) David asked God to create a clean heart and a right, persevering, steadfast spirit in him. This is an example of true repentance and a great example of recognizing that something in him needed to change. Many times we repent, but do we recognize that something in us may also need to change. As children of God, we need to realize that God has given us, the believer, power to overcome sin and not to give in to it.
