We do not always think of repentance as worship, but it can be much easier to sing a rousing hymn than to turn away from our favorite sin.

A sinful act involves worship of the wrong kind, submitting ourselves at that moment to serve the appetites of our pride or lust, and so repentance is literally a transfer of our worship back to the One who rightfully owns it…

Worship has been misunderstood as something that arises from a feeling which “comes upon you,” but it is vital that we understand that it is rooted in a conscious act of the will, to serve and obey the Lord Jesus Christ. The feelings, the joy of having been forgiven, follow on as a consequence of our reunion with him.
