I will extol thee, O LORD; for Thou hast lifted me up, and hast not made my foes to rejoice over me.
O LORD my God, I cried unto Thee, and Thou hast healed me.
O LORD, Thou hast brought up my soul from the grave: Thou hast kept me alive, that I should not go down to the pit.
Sing unto the LORD, O ye saints of His, and give thanks at the remembrance of His holiness.  For His anger endureth but a moment; in His favour is life: weeping may endure for a night, but joy cometh in the morning.  And in my prosperity I said, “I shall never be moved.”
LORD, by Thy favour Thou hast made my mountain to stand strong: Thou didst hide Thy face, and I was troubled.  I cried to Thee, O LORD; and unto the LORD I made supplication. What profit is there in my blood, when I go down to the pit? Shall the dust praise Thee? Shall it declare Thy truth?
Hear, O LORD, and have mercy upon me: LORD, be Thou my helper.  Thou hast turned for me my mourning into dancing: Thou hast put off my sackcloth, and girded me with gladness; to the end that my glory may sing praise to Thee, and not be silent. O LORD my God, I will give thanks unto Thee for ever.

Psalm 30:1-12

This is a Psalm of David which  was sung at the dedication of the house of David.

David was a man greatly blessed by God, who was the first and only king of Israel whom the LORD referred to him, “As a man after my own heart.”

This is a song of praise.

Christians are followers of Jesus Christ alone.  We are to worship Him and praise Him with our mouth and with our lives; loving Him, and living for His glory.
