'O God' in the Bible

Jude, a slave of Jesus Christ, and the brother of James, to those who have been called, who are dear to God the Father and have been kept through union with Jesus Christ;

Dear friends, since I am eager to begin a letter to you on the subject of our common salvation, I find myself constrained to write and cheer you on to the vigorous defense of the faith delivered once for all to God's people.

Now, may there be honor and majesty and power to God, who is able to guard you people from stumbling [and falling away from Him, See Gal. 5:4], and [who is able] to place you before His glorious presence without any [moral] blemish, but with great joy.

to God our Savior, who alone is wise, be glory and majesty, dominion and power, both now and forever. Amen.
