Feelings are great liars. If Christians worshipped only when they felt like it, there would be precious little worship. We think that if we don’t feel something there can be no authenticity in doing it. But the wisdom of God says something different: that we can act ourselves into a new way of feeling much quicker than we can feel ourselves into a new way of acting. Worship is an act that develops feelings for God, not a feeling for God that is expressed in an act of worship.
