How did David respond to God after he sinned with Bathsheba?
David responded by begging God for forgiveness. After being convicted of his adultery with Bathsheba and the murder of Uriah, he poured out his heart in the Psalms, pleading for forgiveness. His deep grief over sin showed he was a true child of God, and it bothered him because of that relationship.
Les explains that David did fall into great sin, yet he did not lose his salvation. David knew how to beg for forgiveness. Although he lived before the age of grace, David is an example of a true child of God: after he was convicted of his sin of adultery with Bathsheba and of murdering Uriah, he poured out his heart in the Psalms, begging for forgiveness. Les points out that David's sin bothered him precisely because he was a true child of God. This also illustrates that grace is not license, so believers should not think they are free to do whatever they want.
