The Assyrian army had surrounded Jerusalem. At that point, King Hezekiah decided, "We are not going to lean on the arm of flesh this time. We are going to do it all God's way!"
The king humbled himself and sought God in prayer: “And it came to pass, when king Hezekiah heard it, that he rent his clothes, and covered himself with sackcloth, and went into the house of the Lord” (Isaiah 37:1). Hezekiah confessed, "Lord, I know I have nothing of myself to give You except my faith. I am helpless in my own strength to fight Sennacherib. We're surrounded by our enemies. Please, give us Your direction!"
Hezekiah knew that Isaiah would have God's word of guidance, so this time he sent his envoy to the prophet. These men said to Isaiah, "The children are come to the birth, and there is not strength to bring forth" (verse 3). In other words: "This time we want to do everything God's way but we have no strength left. What should we do?"
Isaiah had God's word for them: "Be not afraid of the words that thou hast heard. . . . I will cause [Sennacherib] to fall by the sword" (verses 6-7). God was saying, "Any enemy of yours is an enemy of Mine now because you have turned the battle over to Me! If anyone talks against you, hurts you or abuses you, it is an attack against Me. I will take care of that enemy, whether human or demonic."
"He shall not come into this city, nor shoot an arrow there, nor come before it with shields, nor cast a bank against it" (verse 33). God says, "Others may be falling all around you, but that doesn't mean a thing. You are walking in covenant with Me and I have promised to do battle against every enemy that assails you."
What a wonderful picture God has given of His power to deliver us from our enemies. The enemy may shoot fiery arrows at us, but they will not strike. Satan may noisily attack us with a huge army of lusts and temptations, but in the end he will turn and run. God has declared, "I will defend every child of Mine who believes in Me enough to lay down his own sword."
