We all know David as the man who slayed the giant Goliath and the “man after God’s own heart”.
On the other hand, in the book of 2 Samuel chapter 11, we learn about how King David committed adultery with Bathsheba and how he had Uriah (Bathsheba’s husband) killed.
Before he was called to be God’s apostle, Saul of Tarsus was one of the great persecutors of Christians.
He went from one house to another, dragging believers on their feet on the way to the prison. He was also present during the stoning of Stephen, who is believed to be the first Christian martyr.
For these reasons, Paul called himself “chief of sinners”.
