“And David said to the men who stood by him, ‘What shall be done for the man who kills this Philistine and takes away the reproach from Israel? For who is this uncircumcised Philistine, that he should defy the armies of the living God?'” (ESV – Read the chapter)
David understood something that the rest of the Israelite army, including Saul, failed to see. The conflict with the Philistines and specifically Goliath here was not simply a battle between two opposing armies. It was a spiritual battle between two opposing Gods. Goliath wasn’t just challenging Israel’s ability to field a suitable champion to face him in battle, he was challenging the efficacy of the God of Israel to oppose him in battle.
As far as the character of our God is concerned then, it is only appropriate that He would respond by sending a young man who was not a warrior and had seen no time in battle to defeat him. In doing so, He created a legend that of all the stories in the Scriptures, is perhaps the most universally beloved.
While there are many lessons to be learned from the narrative here, let me offer one now. The battles we face in our lives are not always what they seem. Sometimes they are purely physical, but much more often they are spiritual. The battle facing us is not really the battle we are in. It is merely the face on the greater conflict.
When the battles in our lives are spiritual, we cannot approach them the same way we would a normal battle. We must approach them with prayer and trust. We should approach them with confidence because, just as David understood, at the end of the day, the battle is the Lord’s. If we lean into Him, we cannot lose. No matter how big the giant before us may loom, victory will be ours.
