Let's Not lose our heads...

Now the Philistines had gathered all their forces at Aphek. And the Israelites were encamped by the spring that is in Jezreel. As the lords of the Philistines were passing on by hundreds and by thousands, and David and his men were passing on in the rear with Achish, the commanders of the Philistines said, “What are these Hebrews doing here?” And Achish said to the commanders of the Philistines, “Is this not David, the servant of Saul, king of Israel, who has been with me now for days and years, and since he deserted to me I have found no fault in him to this day.” But the commanders of the Philistines were angry with him. And the commanders of the Philistines said to him, “Send the man back, that he may return to the place to which you have assigned him. He shall not go down with us to battle, lest in the battle he become an adversary to us. For how could this fellow reconcile himself to his lord? Would it not be with the heads of the men here? Is not this David, of whom they sing to one another in dances,
‘Saul has struck down his thousands,
and David his ten thousands’?”
(1 Samuel 29:1-5 ESV)
David had successfully kept Ashish at arm's length, not realizing that he was just using him for safety for himself and his men from Saul's wrath.  Achish was totally unsuspecting.  Not so with the rest of the Philistine leaders. They had a more objective view:  this man had cut off the head of their champion, Goliath, and had killed many Philistines in battle. They were not about to lose their heads by letting him infiltrate their ranks. Thus, God did what he can and does so often do in accomplishing His plan despite the predicaments we get ourselves into: he uses the clear thinking of these pagan leaders to release David from the quandary he had gotten himself into: he will not have to chose fighting against Saul or the one who had trusted him with his head.
How has God used others, even unknowingly, to keep you from your own fears, stupidity, and lack of faith or obedience?  He does it. He does it well. He does it faithfully.  May we not test Him to see how often He does so.
