Charles H. Spurgeon on Psalms 12:4

It need not now seem strange to tell you that the Lord is the owner of our bodies, that he has so much propriety therein that they are more his than ours. The apostle tells us as much. 1 Corinthians 6:20. "Glorify God in your bodies which are his." Our bodies, and every member thereof, are his; for if the whole be so, no part is exempted. And therefore they speak proud things, and presumptuously usurped the propriety of God, who said, "Our lips are our own;" as though their lips had not been his who is Lord and Owner of all, but they had been lords thereof, and might have used them as they list. This provoked God to show what right he had to dispose of such lips and tongues, by cutting them off. David Clarkson.
