A musician is not recommended for playing long, but for playing well; it is obeying God willingly, that is accepted: the Lord hates that which is forced, it is rather a tax than an offering. Cain served God grudgingly; he brought his sacrifice, not his heart. To obey God's commandments unwillingly is like the devils who came out of the man possessed, at Christ's command, but with reluctancy and against their will. Good duties must not be pressed and beaten out of us, as the waters came out of the rock when Moses smote it with his rod; but must freely drop from us, as myrrh from the tree, or honey from the comb. If a willing mind be wanting, there wants that flower which should perfume our obedience, and make it a sweet-smelling savor unto God. by T. Watson.
