By the word of the LORD the heavens were made, and by the breath of his mouth all their host. – Psalm 33:6
After a call to worship, the bulk of Psalm 33 is about why God is worthy to be praised.
We see one of those reasons in verse 6, in that by Yahweh’s word, the heavens were made, and by the breath of His mouth, the stars and planetary bodies were made. There may very well be an allusion here to the Son, who is the Word (John 1:1) and the Holy Spirit. (The word translated “breath” is also translated “spirit”.)
But if that’s not the main reason the psalmist uses the words word and breath, they also speak loudly about God’s unmatched power. Who else could create the universe with just His word? He merely spoke it forth, and the heavens were made. He simply breathed to create the trillions of stars and planets. The psalmist is declaring God’s amazing omnipotence.
The psalmist gives another example in verses 7-9. God is able to contain the mighty sea. He is able to say to the terrifying ocean, “Go here and no further.” The sea swallows up men and ships alike, but God controls it by His word. Verse 9 says,
He spoke, and it came to be; he commanded, and it stood firm. – Psalm 33:9
The psalm will later end with a corporate commitment to trust in God, and that absolutely makes sense. With a right understanding of God’s might, how could we not trust Him? He is sovereign over the heavens, the sea, and everything. He is sovereign, then, over everything that goes on in our lives.
