My heart is glad because I have set the Lord always before me.

Psalm 16:1-11
I said to the Lord "you are my Lord; I have no good apart from you."
The Lord is my chosen portion and my cup; you hold my lot.
I have set the Lord always before me; because he is at my right hand, I shall not be shaken.
Therefore my heart is glad, and my whole being rejoices; my flesh also dwells secure.
You make known to me the path of life; in your presence there is fullness of joy; at your right hand are pleasures forevermore.
Why?
All my good is the blessing of the Lord, he is the spring of the goodness.
Set the Lord always before me: let the Lord is my first priority in my daily life.
My heart is glad, my whole being rejoices and my flesh dwells secure is the greatest life in the world.
How wonderful that God make me know the path of life, there is fullness of joy. My joy are come from the Lord.
How?
Praise the Lord! He is the living God.
