Pure in heart (Psalm 73)

Psalm 73
Surely God is good to Israel to those who are pure in heart.
I envied the arrogant when I saw the prosperity of the wicked. They say " How can God know? Does the most High have knowledge?"
The wicked, they always carefree, they increase in wealth. It is common scenario in this world.
Surely in vain have I kept my heart pure; in vain I washed my hands in innocence. -- a command of the sad man have been plagued.
When I tried to understand all this, it was oppressive to me, till I entered the sanctuary of God, then I understood the final destining. It is could not be explained by human mind.
As a dream when one wakes, so when you arise, O Lord, you will despise them as fantasies.
Solution:
Yet, I am always with you; you hold me by my right hand.
Whom have I in heaven but you; And earth has nothing I desire besides you?
My flesh and my heart may fail; but God is the strength of my heart and my portion forever.
Action:
As for me, it is good to be near God. I have made the Sovereign Lord my refuge; I will tell of all your deeds.
Why?
The mind of David is same as ours'.
When I could not understand or lost the courage to follow the Lord, come to the present of the Lord, come to the sanctuary. Listen to the words of the Lord.
Our life is temporary and short, like a dream, we have the everlasting place in heaven.
My hope is the God. Remember the grace of the Lord has done for us.
How?
O Lord, Please let me see what you see, understand what your mind, let me getting closer to you.
I have made the Lord be my refuge; I will tell all of your deeds.
