After the author had focused his attention on God and his works, he now spurs himself on to praise this mighty God, and he expresses this in song and music. He intends to make this his life’s program. As long as he has breath, he wants to praise his Maker.
This great God, after all, is his God. He feels a personal connection with the Lord. That is why he began already in Psalm 104:1, by saying my God.
And he says that again here towards the end of his song. This awesome God is for him actually close by, gloriously close by.
We often find the intense desire to praise this God in the psalms (for example, Psalm 7:17; Psalm 13:6; Psalm 18:49). It is written in a moving manner in Psalm 63:4: So I will bless you as long as I live; in your name I will lift up my hands.
By the way, the whole Bible is full of this. The apostle Paul encourages his readers in Ephesus—and therefore us as well!—with these words: “singing and making melody to the Lord with your heart, giving thanks always and for everything to God the Father in the name of our Lord Jesus Christ” (Ephesians 5:19–20). Here, we also discover the secret, for which we can thank this great God. It is Jesus, who can give us the strength to always
be able to praise God.
33 I will sing to the LORD as long as I live; I will sing praise to my God while I have being.
