Our LORD is to be exalted because He is holy, and also because He is a righteous judge. That’s stated in verse 4. Although He has all the power, He doesn’t wield it like a dictator. His judgement is always fair and right, never influenced by a bad mood or emotional moment. As a result, His people worship at His footstool. In the Old Testament, “footstool” is sometimes used in place of the ark of the covenant, for the temple on Mount Zion, or as the whole earth. When you picture the entire earth being a footstool, you get a pretty good idea of the greatness of our God! We are called to bow down with awe and thanksgiving before the God who is righteous and holy. We also worship in joyful hope for the day when every knee will bow and every tongue confess that Jesus Christ is Lord.
