Psalms 51:14-15

Psalms 51:14-15. Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness. O Lord, open thou my lips; and my mouth shall show forth thy praise.

David is going to preach, and to sing, too; and he will do it all himself; just now he wants nobody to help him. He is so given up to the service of his Master that he will be preacher and preceptor, too. He will say, and he will sing, that God is a righteous God That was a singular theme for a blood-washed sinner: "My tongue shall sing aloud o! thy righteousness." But, believe me, nobody understands the righteousness of God but the man who understands sin, and who also understands the wondrous mercy by which it is put away through the bleeding sacrifice of Christ. When we have reached that point, then can we, and then will we, show forth his righteousness.
