This and more thoughts on worship leading from my friend Bob Kauflin at Worship Matters:

"If you lead corporate worship, my hope is that you believe the Holy Spirit can work not only through what you’ve planned, but also through leadings and impressions that occur during the meeting. Without being dependent on them or exaggerating their importance, they’re one more way God can demonstrate the overflow of his love which was most clearly demonstrated in the substitutionary death of the Savior at Calvary."
