'O God' in the Bible

But thanks be unto God, who always leadeth us in triumph in Christ, and maketh manifest through us the savor of his knowledge in every place.

For we are a sweet savor of Christ unto God, in them that are saved, and in them that perish;

And such confidence have we through Christ to God-ward:

Knowing therefore the fear of the Lord, we persuade men, but we are made manifest unto God; and I hope that we are made manifest also in your consciences.

For whether we are beside ourselves, it is unto God; or whether we are of sober mind, it is unto you.

We are ambassadors therefore on behalf of Christ, as though God were entreating by us: we beseech you on behalf of Christ, be ye reconciled to God.

But thanks be to God, who putteth the same earnest care for you into the heart of Titus.

ye being enriched in everything unto all liberality, which worketh through us thanksgiving to God.

For the ministration of this service not only filleth up the measure of the wants of the saints, but aboundeth also through many thanksgivings unto God;

Thanks be to God for his unspeakable gift.

Now we pray to God that ye do no evil; not that we may appear approved, but that ye may do that which is honorable, though we be as reprobate.
