Worship Our Holy God
This is an enthronement psalm that pictures the Lord taking up His Davidic throne and ruling the earth from Jerusalem (Zech 14:9). The main point of this psalm is that the Lord is holy and should be exalted.
The first section of the psalm introduces the idea: Our Holy God is Great (1-3). All the peoples of the earth are called to fear YHWH (1). Christ is King, and one day will rule His creation physically from Zion (2). Everyone should praise the awesome and great name of the Lord (2-3). Holy is He!
The second section continues: Our Holy God is Just (4-5). The King loves justice, and His strength is exerted in establishing what He loves (4). The Lord will establish and sustain a just and righteous society over all the earth (4-5).
The third section continues: Our Holy God is Merciful (6-9). God responded in the past to the cries of His priests on behalf of the people (6). He gave them His Law, which governed the behaviour of His people so that they would be a holy people (7). Even when they continually went astray, God forgave them. Yet the consequences of their sins they could not escape; for God is a just God (8). Worship Him alone, for our God is holy (9).
Brethren, three times the psalmist calls God “holy.” Three times all people are called to praise Him for His works and for His perfections. God is utterly separate from anything in His creation. He is perfect and distinct from any created thing. He is great and awesome in His power. He is just and righteous in His actions. He is merciful in His love for His people, forgiving our sins. Worship Him for holy is YHWH our God!
