Ps 97 1The LORD reigns, let the earth be glad;
let the distant shores rejoice.The Psalmist is saying that we should not be anxious or sad because God controls all of creation. If God controls all of creation then He will protect us because He controls the earth.. This is why God is holy because we see all of these events in creation and He is orchestrating them from heaven on our behalf. God is holy because He is concerned for us holistically. When we speak this Psalm it should cheer us up.
2Clouds and thick darkness surround him;
righteousness and justice are the foundation of his throne. God is mysterious because He does not always explain the reasons for the events on the earth. But He will not act apart from His righteousness and His justice. God has a throne which is all of His plans from eternity past in decreeing whatsoever comes to pass. He is decreed whatever comes to pass on the foundation of His righteousness. He has given Israel the curses in the same language of fire, wind and heat that purifies seven times.12  6And the words of the LORD are flawless, like silver refined in a furnace of clay,purified seven times. God simply speaks and the mountains melt. He has given us the words of melting the enemies of God.  
3Fire goes before him and consumes his foes on every side."The Psalmist is speaking of Gods protection of Israel as the fire that went out in front of them to destroy their enemies as He led them out of Egypt.God acted righteously in  leading them to the promise land by judging their enemies.
4 His lightning lights up the world; the earth sees and trembles". He is teaching that as we speak the axioms that Gods fire could melt the mountains through the curses.
  5The mountains melt like wax before the LORD ,before the Lord of all the earth. His fire that destroyed the enemies of Israel could melt the mountains.As we speak this Psalm we see the interaction between speaking the curses and our God who has the darkness of mysterious power that has been written down in the axioms. We speak words that God decides to use according to His control and power.
 6The heavens proclaim his righteousness, and all the peoples see his glory." God protects Israel as we speak the axioms as the God who is in the heavens controlling all the events on the earth. This God does these great events to save His people. He is smiling on His elect in the event. So the whole world is under the heavens and witnesses Gods works.
 7All who worship images are put to shame, those who boast in idols- worship him, all you gods!God is saying that these gods have no control over the earth. They are dead gods. So he calls on those gods to give Him the glory of controlling the earth. Through the curses the nations who worship these  gods suffer under the control of His people.
8Zion hears and rejoices and the villages of Judah are glad because of your judgments, O LORD .
9For you, O LORD , are the Most High over all the earth; you are exalted far above all gods. When God answers the pronouncements the people of Judah rejoice. God proves that He is a covenant keeping God by destroying the enemies of Israel. We have the words that move God who controls all things.10   Let those who love the LORD hate evil,
for he guards the lives of his faithful ones
and delivers them from the hand of the wicked.
11  Light is shed upon the righteous
and joy on the upright in heart.
 12  Rejoice in the LORD , you who are righteous,
and praise his holy name.Let the people pronounce  the law, covenants, curses, statutes,promises and decrees. They will not depart from this word but will meditate on it night and day. These faithful ones will be delivered by this holy God who controls all of creation by the word of His mouth. Let them respond with praise when God answers their prayers. We must speak the axioms so that we are always looking for this God to act in the big events of creation. Knowing that our God controls the entire creation and protects us will make us always be joyful
