“If the essence of worship is satisfaction in God, then worship can’t be a means to anything else. You simply can’t say to God, “I want to be satisfied in You so that I can have something else.” Because that would mean that you are not really satisfied in God but in that something else. And that would dishonor God, not worship Him.
But in fact, for many people and pastors, the event of “worship” on Sunday morning is conceived of as a means to accomplish something other than worship:
We “worship” to raise money;
We “worship” to attract crowds;
We “worship” to heal human hurts
We “worship” to recruit workers;
We “worship” to improve church morale;
We “worship” to give talented musicians an opportunity to fulfill their calling;
We “worship” to teach our children the way of righteousness;
We “worship” to help marriages stay together;
We “worship” to evangelize the lost among us;
We “worship” to give our churches a family feeling, etc., etc.
In all of this we belittle worship and God.”
