Because of the character of God, previously spoken of in the prior verses, then praises become appropriate toward God for all that He is, for all that He does, and for all that He provides for those who have placed themselves in the knowledge of Him, through their spiritual growth from learning, and have placed themselves in His care and refuge by means of that same spiritual life.
God will destroy evil and protect good. God will be a refuge from evil, for all who look to Him for that protection.
And given the big picture of life in all of its infinite possibilities for ones personal life, now and in eternity, then God is due some form of praise.
And who does this praise originate from?
From those who dwell with God, in Zion.
And so how many of you live on that mountain in Jerusalem? Well, most likely none of you live there.
But the mountain called Zion is not a geographic location, but the symbolism of spiritual maturity and the completeness of ones life.
Israel is the identification of Gods chosen people. It represents the masses of people that make up Gods nation (believers in Christ).
Jerusalem, is the city of peace, symbolizing those who have advanced significantly in their spiritual lives, to attain spiritual maturity (spiritually mature believers).
Zion is the mountain inside of Jerusalem, which symbolizes the massive knowledge, understanding, and wisdom of God (doctrine), both known and possessed by those inhabitants of spiritual maturity.
There are many believers within the nation of Gods chosen, but not all live inside the spiritual maturity sphere, because not all have taken the time to learn, know, and understand doctrine, which is the source of truth, and the basis for all of our relationship with God.
So, if you begin to understand the symbolisms being expressed in this verse and throughout the Old Testament, and the Bible on the whole, then you begin to understand life in general, and Gods overall plan for your life, specifically.
Prior to your birth, you were nothing. God took a speck of dust (the biological you) and imputed human life (you) into that speck of dust. On your own (dust) you are nothing. With Gods word (doctrine) in you, you become something phenomenal, because of His effort, not from your own effort.
That then is worth some praise. It is not?
