Invisibly working

Ray Van Neste encourages preachers to remember that even when our own efforts are inadequate, God's power is sufficient:

Anyone who has preached much knows the agony of it. . . . You have just laid out your heart with all the earnestness you have, and as you sit down you are painfully aware of the inadequacy of your efforts. And this feeling is augmented because the inadequacies which are so evident to you have just been publicly displayed before the people of God!

What does God require of us to provide his power? Preach the Word of God.
