Now slothfulness IS a sin, but waiting is of God. If I plead anything, it is the sin of sloth, not the virture of waiting. It is astounding that the Almighty would wait until one of His creatures learned to wait. I don't understand this, but there it is. God's purpose is right on time, but He does wait in order to be gracious.
Men show no interest and fall away from the gospel.
Those in whom you put confidence are rarely seen. The worship is a sleepy-eyes business, and interest wanes to the point of excruciating deadness. He's waiting that He may be gracious unto you. Preach the gospel of a redeeming Savior, and do what you know while you wait. Walk in Christ, for He is the way.
