1 Chronicles 21-23

Even though David was a man always seeking God's heart and will the beginning of chapter 21 reminds us that the prophet/king was only human. Just like Judas David plunged head-long into Satan's plan to dishonor God. Unlike Judas when David realized his sin he did not take judgment into his own hands. Instead he surrendered to the cross (though he couldn't have know that at the time) and sought out the mercy of God for his forgiveness. I assume that the 70,000 killed in God's plague may have been those who wee boasting in what Israel could accomplish with such a large army and not giving God the credit for blessing Abraham's seed as was now evident. God displayed his power to over come sin by turning the point where judgment halted, a display of mercy and grace, into the holiest sight of woship under the law. Oman's threshing floor was where judgment was stopped. After David arrived there it became the place of mercy and forgiveness.
It took me about 15 minutes to read this passage.
