1 Samuel 29:1-5 (ESV)
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’?”
The above story tells us a lot about the fears of men. David was a threat to the Philistines. When God is with you, others fear you. It is a very simple truth. David’s reputation went before him.
Notice in the New Testament a similar comparison:
Acts 4:13 (ESV)
Now when they saw the boldness of Peter and John, and perceived that they were uneducated, common men, they were astonished. And they recognized that they had been with Jesus.
When the people of God spend time with God the men of the world take notice. In the story of David, we have to admit, he was not exactly living with God at the time of these events. He was living in fear. Yet, his reputation as being a man of God somehow caused fear in the hearts of the Philistines. So, perhaps even weak Christians can be used by God. Moses was weak and God used him. Jonah was weak and God used him. Peter was weak and God used him. I am weak ... can God use me?
