'O God' in the Bible

We give praise to God at all times for you, keeping you in memory in our prayers;

Being conscious, my brothers, dear to God, that you have been marked out by God's purpose;

For they themselves give the news of how we came among you; and how you were turned from images to God, to the worship of a true and living God,

So that your lives might be pleasing to God, who has given you a part in his kingdom and his glory.

And for this cause we still give praise to God, that, when the word came to your ears through us, you took it, not as the word of man, but, as it truly is, the word of God, which has living power in you who have faith.

Who put to death the Lord Jesus and the prophets, violently driving us out; who are unpleasing to God and against all men;

For how great is the praise which we give to God for you, and how great the joy with which we are glad because of you before our God;

And last of all, the prayer which we make to you from our heart and in the name of the Lord Jesus, is this: that as we made clear to you what sort of behaviour is pleasing to God, as in fact you are doing now, so you will go on in these ways, but more and more.
