It seems to me that a lot of Psalm 46 is telling how the end of the world will come about. God will destroy the nations and wars will cease. All of this destruction of nations and wars will show how glorious God is. Then God says, 10 "Cease striving (be still) and know that I am God; I will be exalted among the nations, I will be exalted in the earth."
But look how cool this is!
7 and 11 The LORD of hosts is with us; The God of Jacob is our stronghold. NASB
The LORD of Heaven’s Armies is here among us; the God of Israel is our fortress. NLT
The LORD of Heaven's Armies! Wow! Here with us!
God is our refuge and strength, a very present help in trouble.
Come, behold the works of the LORD.
Be still and know that He is God.
The LORD of Heaven's Armies is here among us.
That should change your entire outlook in life.
