In just a few lines we are given a profound vision of the King of Glory.
In this vision we find Jehovah in His regal majesty, like a robe. Underneath we catch a glimpse of divine battle armor because He is a king of action. Indeed, He has put this on Himself. It’s not a status or power conferred from some other source, but an authority inherent in His Person. He has made all things and the world is subject to His will alone; no one else can interfere with His reign.
Go ahead and make some attempt to trace the genesis of His reign. You won’t find it because it started before anything else that existed.
Imagine the most powerful force in this world. Many would say it’s the oceans, with it’s unknown murky depths housing things men never see and able to pound the shores of the world, pulverizing all it touches. When it gets stirred up, nothing man can do withstands that mighty power. The noise alone is more than most human ears can tolerate. Combine all the stormy seas into one vast power, if you can imagine it. Yet the Lord in His majesty is unmoved because He made the sea with the hollow of His hand. The waves obey His commands.
And when He testifies of His moral character, when He reveals His personal law for Creation, there is no authority in any position to challenge Him. When He speaks, it is the end of every matter. His divine courts define holiness and they have no terminus.
