“Deliver me from the guilt of bloodshed, O God,
The God of my salvation and my tongue
Shall sing aloud of your righteousness.”
Psalm 51:14 

A man consulted a doctor. “I’ve been misbehaving, Doc, and my conscience id troubling me,” he complained. “And you want something that will strengthen your will power?” asked the doctor. “Well, no,” the man said. “I was thinking of something that would weaken my conscience.”

Many people respond this way to sin. They know what they are doing is wrong and they may even confess it, but they don’t want to repent – they want to hold on to their sin and get rid of their guilt. You can’t have it both ways!
