This Psalmist did not fear when an army encamped against Him or war rose against Him because the all powerful Lord of Sabaoth was with Him. When a thousand fall at his side and ten thousand at his right hand the Christian must not fear because the Lord is his refuge and the Lord is more powerful than all the armies of the world. Even when there are no Christians nearby the power of God is present and at work against His enemies.
So he answered, “Do not fear, for those who are with us are more than those who are with them.” II Kings 6:16 NKJV
Often in Scripture we read of God’s people facing terrible odds on the field of battle. Gideon had 300 men against an army of Midianites so large that Scripture simply tells us “their camels were without number”. David was a young shepherd without armor against the champion of the Philistine army who stood nine feet tall and had a spear like a weaver’s beam. King Hezekiah had but few soldiers in comparison to at least 186,000 Assyrians that were camped around Jerusalem. And yet, in all of these situations, God’s people enjoyed massive victories at the hand of the Lord. We do not read of massive angelic armies surrounding Gideon or Jerusalem like at Dothan so how was it that God’s people enjoyed victory?
It is not only the angels of the army of the Lord that are with the Lord’s people but also the Lord God Himself. He is called the Commander of the armies of the Lord (Joshua 5:13-15), the Lord of Sabaoth, the Lord of Hosts. The Lord is with His armies, He leads His armies, and He is the power of His armies. His power is so great that He does not need armies of angels though He has seen fit to have legions upon legions of them at His disposal. When David went against Goliath, Gideon against the Midianites, Jehoshaphat against the Moabites, Ammonites, and the people of Mt. Seir, the Lord of Sabaoth went before them and by His might He gave great victory to His people. The Lord God is omnipotent, He is all powerful such that nothing can be compared to His might, and He is with us.
