Jehovah is not “mighty”, only because of what He does. He is God all by Himself. He is the King of kings and the Lord of lords. He is the creator of the universe. He is without antecedent. He wasn’t made, He existed before time began. He is glorious, majestic and magnificent. That is why people like Solomon spared no cost in worshipping Him. That is why the Hebrew boys declared what they said in Daniel 3:13-18. There is no other god besides Him. He remains God, even when we don’t get what we desire.
