All those activities of worship require the exertion of our will. But they do not become genuine worship by virtue of that. Sure they do. But their heart is still far away from God. The reason is that the drawing near of the heart to God means the coming alive of our feelings for God.
Worship is an affair of the heart.
It is an affair of feeling and of emotion. I feel right now in an almost impossible pastoral position. What I want to say can be so easily categorized and dispensed with as emotionalism on the one hand or dead decency on the other, depending on your personality and experience. We live in a peculiar time. On the one hand, fascination with feelings is rampant.
