"When David had sinned but in one instance with Bathsheba, interrupting the course of a holy life by one, sad calamity, it pleased God to pardon him, but see upon what hard terms; he prayed long and violently, he wept sore, he was humbled in sackcloth and ashes, he ate the bread of affliction and drank his bottle of tears; he lost his princely sprit, and had an amazed conscience; he suffered the wrath of God, and the sword never did depart from his house. His son rebelled, and his kingdom revolted; he fled on foot, and maintained spies against his own child; he was forced to send an army against him that was dearer than his own eyes, and to fight against him whom he would not hurt for all the riches of Syria and Egypt; his concubines were defied by an incestuous mixture, in the face of the sun, before all Israel; and his child was the fruit of sin, after a seven day's fever, he died, and left him nothing of his sin to show, but sorrow and scourges of the divine vengeance; and after all this God pardoned him finally, because he was for ever sorrowful, and never did the sin again. 

  Now he that has sinned a thousand times for David's once, is too confident if he thinks that all his shall be pardoned at a less rate than  was used to expiate the one mischief of the religious King David."   Jeremy Taylor.
