God has prepared His throne. He did not just happen to sit as king. He prepared. His kingdom ruleth over all. He has set up a kingdom. There is nothing over which God does not have control.
God’s angels and His heavenly hosts excel in strength and do what He commands They help to carry out what He wants done. “20Bless the LORD, ye his angels, that excel in strength, that do his commandments, hearkening unto the voice of his word. 21Bless ye the LORD, all ye his hosts; ye ministers of his, that do his pleasure.” (Psalm 103:20,21)
God is great. He rules over all. Nothing takes Him by surprise. He is in control of all. God’s angels and heavenly host do His bidding wherever He sends them. Therefore, all of God’s works in all parts of His dominion bless Him. That is, they adore Him and kneel before Him, or show Him reverence, obedience. Because I know God is in control, I can bless the Lord too. “Bless the LORD, all his works in all places of his dominion: bless the LORD, O my soul.” (Psalm 103:22)
