“The voice of the LORD is powerful; the voice of the LORD is full of majesty” (v4). This song calls for all creation to give the Lord “the glory due His name” (v1-2). God’s voice, His creative power, “breaks the cedars …flashes forth flames of fire … shakes the wilderness” (v4-9). God sits “enthroned” over the mightiest forces of our universe, even the floods and storms (v10), and in His temple, all creation cries “Glory!” (v9).
“May the Lord give strength to His people!” (v11). Because we are covered by Christ’s righteousness, forgiven and made holy, we don’t have to fear God; His awesome power instead is our strength and help.
