Seeking a Pure Heart

Seeking a pure heart:

How to confess your sins

Dr. Jim Denison

Psalm 51

Why do we sin?

Here’s the background of Psalm 51. King David had an affair with Bathsheba, the wife of Uriah. She became pregnant. To cover his sin, eventually he had Uriah killed and took the widow as his wife. But God knew what he had done, and sent the prophet Nathan to expose his sin.

In this one event David broke nine of God’s Ten Commandments. He broke in order the tenth, coveting his neighbor’s wife; the seventh, by committing adultery; the eighth by stealing her for himself; the sixth by murdering her husband; the ninth, by lying about his sin; the fifth, by dishonoring his parents; the second, by making an idol of Bathsheba; and the first and third, by shaming God and his name. At least he didn’t break the Sabbath, that we know of.

Why did he do this? Why do we sin? Why do these things happen? Let’s do some theology together.

First, we have inherited a sin nature.

Verse 5 is clear: “Surely I was sinful at birth, sinful from the time my mother conceived me.” This verse does not mean that babies or fetuses sin; it means that we have all inherited a sin nature, a propensity to sin.
