The document discusses lessons that can be learned from 2 Samuel about King David's life. It describes how David grieved for King Saul, waited patiently to become king at age 30 and ruled for 40 years. It also discusses how David showed kindness to Mephibosheth, the grandson of Saul, and wept deeply when his son Absalom was killed. However, it also notes David disobeyed God by taking many wives and numbering his army, and committed adultery with Bathsheba. The document cautions that good times can tempt one to indulge desires at the cost of a holy life.
