What does Psalm 29:1 mean?

This first and last verses of Psalm 29 mention the Lord's strength. Omnipotent—literally meaning "all-powerful"—is one of God's descriptors. Anything which can be done, He can do. Nothing is too hard for Him. God is also glorious. "Glory" is typically used to describe something that makes God's nature and wonder apparent. In some cases, this means the visible manifestation of His divine power. David calls upon the heavenly beings to attribute glory and strength to the Lord.

Similarly, Psalm 96:6 refers to strength and beauty as being in the Lord's sanctuary. Wherever the Lord is, strength and glory accompany Him. Heavenly beings associate glory and honor and thanks with God, according to Revelation 4:8–11, where twenty-four elders join in their praise. They say, "Worthy are you, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they existed and were created" (Revelation 4:11).

It should comfort and encourage believers to know the Lord has unlimited strength and glory. Paul was uplifted by knowing this fact. He writes in Philippians 4:13: "I can do all things through him who strengthens me."
