"As surely as the LORD lives, you have been honest and I would be pleased to have you serve with me in the army. From the day you came to me until today, I have found no fault in you." (1 Samuel 29:6)
The Philistine commanders see David and his men marching with Achish and object: send the man back; he must not go into battle with us; what better way could he reconcile himself to his master than by taking the heads of our own men? Achish sends for David: As surely as the LORD lives, you have been honest and I would be pleased to have you serve with me in the army. From the day you came to me until today, I have found no fault in you. But the rulers don't approve of you. Turn back and go in peace. David protests: what have I done? But Achish insists. David returns to Ziklag.
The episode is a providential rescue: David was about to be compelled to fight against Israel, his own people and his destined kingdom. The Philistine commanders' objection, which seemed like rejection, was God's protection. David did not know it at the time and was genuinely frustrated. But God used Philistine suspicion to prevent the catastrophic consequence of David's own strategy. The Catechism identifies this as the pattern of divine providence working through events that appear adverse (CCC 303).
Brothers and sisters, the rejection that seems like a setback is sometimes the protection that prevents the catastrophe. David was frustrated to be sent back. He could not yet see that God was steering him away from fighting Israel. The door closed by the Philistine commanders was the door through which God kept the covenant purposes intact. Trust the closed door.
Lord God, use even Philistine suspicion to protect us from the consequences of our own strategies. When doors close in our faces, give us the faith to see your hand in the closing. Through Christ our Lord. Amen.
