Choosing to fight a spiritual battle physically is a foolish choice.
David came up against Goliath knowing that the battle was not to be won in the physical. The armor and weapons and he chose show us that.
37 And David said, “The LORD who delivered me from the paw of the lion and from the paw of the bear, He will deliver me from the hand of this Philistine.” And Saul said to David, “Go, and may the LORD be with you.” 38 Then Saul clothed David with his garments and put a bronze helmet on his head, and he clothed him with armor. 39 David girded his sword over his armor and tried to walk, for he had not tested [them.] So David said to Saul, “I cannot go with these, for I have not tested [them.]” And David took them off. 40 He took his stick in his hand and chose for himself five smooth stones from the brook, and put them in the shepherd’s bag which he had, even in [his] pouch, and his sling was in his hand; and he approached the Philistine.[1Sa 17:37-40 NASB]
David went into battle with the only weapon he needed, the knowledge of His God and who it was he served. He saw himself as vessel to be picked up by God and used and not the one that was truly fighting. He was only there to do as His almighty God would have him do.
45 Then David said to the Philistine, “You come to me with a sword, a spear, and a javelin, but I come to you in the name of the LORD of hosts, the God of the armies of Israel, whom you have taunted. 46 “This day the LORD will deliver you up into my hands, and I will strike you down and remove your head from you. And I will give the dead bodies of the army of the Philistines this day to the birds of the sky and the wild beasts of the earth, that all the earth may know that there is a God in Israel, 47 and that all this assembly may know that the LORD does not deliver by sword or by spear; for the battle is the LORD’S and He will give you into our hands.” 48 Then it happened when the Philistine rose and came and drew near to meet David, that David ran quickly toward the battle line to meet the Philistine. 49 And David put his hand into his bag and took from it a stone and slung [it,] and struck the Philistine on his forehead. And the stone sank into his forehead, so that he fell on his face to the ground. 50 Thus David prevailed over the Philistine with a sling and a stone, and he struck the Philistine and killed him; but there was no sword in David’s hand.[1Sa 17:45-50 NASB]
What is your battle today? What are you running away from? What armor are you trying to put on? Instead of running, stand in a place to be used by God in this battle – usually that is on your knees in prayer to our almighty God and Father. He never leaves us nor forsakes us (Deut 31:6).
17 The LORD hears his people when they call to him for help. He rescues them from all their troubles. 18 The LORD is close to the brokenhearted; he rescues those whose spirits are crushed.[Psa 34:17-18 NLT]
