Integrity is built by defeating the temptation to be dishonest; humility grows when we refuse to be prideful; and endurance develops every time you reject the temptation to give up.
Rick WarrenWorship is a powerful witness to unbelievers-if God's presence is felt, and if the message is understandable. God's presence must be sensed in the service. More people are won to Christ by feeling God's presence than by all our apologetic arguments combined. Few people, if any, are converted to Christ on purely intellectual grounds. It is the sense of God's presence that melts the heart and explodes mental barriers.
