Ascribe to the LORD, O heavenly beings, ascribe to the LORD glory and strength. Ascribe to the LORD the glory due his name; worship the LORD in the splendor of holiness.
This is one of the most compelling calls to worship ever given. It describes God as He is and calls us to recognize Him and re-order ourselves accordingly. God is great, powerful, loving and glorious and deserves our worship. Thus worship involves our conscious acknowledgement of His rulership over us and His greatness demonstrated to us.
But the last phrase of this call to worship is what I find to be particularly compelling. The Lord's holiness is a quality of great beauty. It is splendorous and magnificent. It is the perfection of His Person that compels us to worship Him. I acknowledge His greatness, power, and glory, but I worship His holiness.
The glory due Your name must come from my heart to Yours. You are holy, wise and powerful. You are great and mighty. But my heart trembles at Your holiness for I am unholy. It is in that knowledge that I realize that You must change me, remake me, and give me a righteousness that pleases You. And through that newly made heart I can worship You in the splendor of Your holiness.
