The pivotal part of this passage is when that which could bring fear hits the Israel’s doorstep, David immediately inquires of the Lord. After he inquires, David get the answer for what He is to do. David trusts God and does exactly what he is supposed to do and God brings the victory. Something interesting happens here. Instead of saying “Do not Fear” to David, he puts the fear of David upon all the nations. The same people, the Philistines, had the same result as they did in the days of Goliath, because David feared God more than he feared people. And and interesting thing happens, the Lord brings the fear of David upon all the nations. Not only was David not fearful, but because of his unwavering trust in the most powerful one, God puts the fear of David upon all the nations. When the glory of God becomes our priority, God will bring his honor, and in this case, fear to all the nations. Read these words that David sang as they came victoriously home:
1 Ch 16:23-26 - Sing to the Lord, all the earth! Tell of his salvation from day to day. Declare his glory among the nations, his marvelous works among all the peoples! For great is the Lord, and greatly to be praised, and he is to be held in awe above all gods. For all the gods of the peoples are idols, but the Lord made the heavens.
We are to declare his glory among the nations, by trusting Him and holding him in awe only. He is the true God who made the heavens and the earth and his people. Fear Him only!!!!
