"So David's fame spread throughout every land, and the LORD made all the nations fear him." (1 Chronicles 14:17)
Hiram king of Tyre sends cedar, carpenters, and stonemasons to build David a palace. More sons and daughters are born to David in Jerusalem. The Philistines hear he has been anointed king and come up to attack. David inquires of God: shall I go and attack the Philistines? Will you deliver them into my hands? God answers: go, I will deliver them into your hands. David defeats them and they abandon their gods, which David orders burned. The Philistines come up again. David inquires of God again and receives different instructions: do not go up; circle around them and attack from in front of the poplar trees. When you hear the sound of marching in the tops of the trees, move out, because that will mean God has gone before you to strike the Philistine army. He does so; the Philistines are routed from Gibeon to Gezer. So David's fame spread throughout every land, and the LORD made all the nations fear him.
David inquires twice and receives two different battle plans. The Catechism identifies this as the principle of fresh discernment for each new situation: yesterday's strategy is not automatically today's instruction (CCC 1788).
Brothers and sisters, David won the first Philistine battle one way and the second a completely different way. He did not assume the second battle would follow the first battle's plan. He asked again. Inquire again, even about situations that look identical to situations you have already resolved. God may have a different plan this time.
Lord God, give us David's discipline of fresh inquiry: not assuming yesterday's answer applies to today's situation, but asking again each time. Through Christ our Lord. Amen.
