1 Samuel & 2 Samuel 1-11 | 1/15/2023. God says in the Scriptures that David was "a man after My own heart" (1 Samuel 13:14). But David also sinned greatly against the LORD, and so he is not only a positive example for us, but a negative one as well. And his great sin of adultery, lying, coveting, and murder is probably worse than you've previously been taught.
