"David replied to the Philistine, “You come to me with sword, spear, and javelin, but I come to you in the name of the Lord of Heaven’s Armies—the God of the armies of Israel, whom you have defied. Today the Lord will conquer you, and I will kill you and cut off your head. And then I will give the dead bodies of your men to the birds and wild animals, and the whole world will know that there is a God in Israel! And everyone assembled here will know that the Lord rescues his people, but not with sword and spear. This is the Lord’s battle, and he will give you to us!” I Samuel 17:45-47
Not only did David know how to fight a giant, he knew why to fight a giant.
Fighting giants is a big job so you better know why and when to do it! As I conclude these thoughts about David and Goliath over the next few days I want to share some giant lessons.
Lesson one: why fight a giant?
David fought the giant to defend God's glory. This defiant giant was impugning God and the armies of God. Not only did he disrespect God but he was causing God's people to despair and to doubt God. Because David was zealous for God and jealous of His honor, this giant had to go! David knew he had to fight the giant to defend the reputation of his God.
Never fight a giant for your own reputation or to make a name for yourself. That is not a good enough cause.
David fought the giant to deliver God's people. Goliath had the army of Israel trapped in fear and despair. His threats and taunts had immobilzed the troops. That was putting them at risk as well as the nation they defended. God called His people to be free. We are not designed for fear. When David recognized that God's people needed to be delivered he knew he had to fight the giant.
Never fight a giant to impress. Only fight a giant if you or others are oppressed. Freedom is a reason to fight giants.
David fought the giant to demonstrate God power. This mammoth hulk of a man was making God's warriors look weak. The giant was causing people to lose their fear of Jehovah and to embolden the enemies bent on destroying them. Not only were the Philistines beginning to believe they could defeat Israel, other enemies were watching closely. When an army marched in those days they carried the banner of their gods, they carried the banners of their tribes, and they carried the flag of their nation. So, in a very real and visible way the army of a nation represented all that nation represented. When an army looked weak, the entire nation and its culture and its religion looked weak. David demonstrated that God's power through a boy is far stronger than the enemies' strongest weapon.
Never fight a giant to demonstrate your strength or power. Only confront a giant to demonstrate that His strength is made perfect in your weakness.
There are reasons for fighting giants. I have given you three of them. David fought Goliath for the right reasons and God honored him with victory.
