'O God' in the Bible

Now, thanks be to God, who always causes us to triumph in the Christ, and sheds in every place, by us, the fragrance of the knowledge of himself.

Knowing, then, the fearful judgment of the Lord, we persuade men; but we are made manifest to God. I hope, indeed, that we are also made manifest in your consciences.

Therefore, we act as ambassadors for Christ, as though God entreated through us; we beseech in Christ's stead, be reconciled to God:

Now I rejoice not that you were made sorry, but that you sorrowed in order to repentance. For you sorrowed in a way acceptable to God, that you might in nothing receive injury from us.

But thanks be to God, who put the same earnest care for you in the heart of Titus:

that you may be enriched in every thing, for all liberality which produces through us thanksgiving to God;

because the administration of this service not only supplies the wants of the saints, but also abounds in many thanksgivings to God;

Thanks be to God for his unspeakable gift.

Yet I pray to God that you may do no evil; not that we may appear as having proof, but that you may do what is good, though we be as without proof.
