The LORD’s Word Is Right and His Word Made the Heavens
God’s trustworthy character and creative speech are joined: the word of the LORD is right, the earth is full of his covenant love, and by his word the heavens were made. Creation responds to command; nothing in the cosmos competes with the Creator.
John 1 and other New Testament texts develop divine Word theology in relation to Christ, but Psalm 33:6 is not itself quoted there as a Christological proof text. The connection is a strong creation-and-Word trajectory and should be labeled accordingly.
