'O God' in the Bible

For so many promises of God, in Him are yes; therefore indeed through him they are Amen unto the glory to God through us.

But thanks be unto God, who always causes us to triumph in Christ, and manifesting the fragrance of his knowledge through us in every place:

because we are a sweet savour of Christ unto God, among those who are saved, and among those who perish;

Therefore knowing the fear of the Lord, we persuade men; but we have been made manifest unto God; and I hope that we have indeed been made manifest in your consciences.

Therefore we are embassadors in behalf of Christ, as God is intreating you through us; we pray you in behalf of Christ, be ye reconciled to God.

But thanks be unto God, who gives this same enthusiasm in your behalf in the heart of Titus;

in every thing being enriched in all purity, which works out through us thanksgiving to God.

Because the ministry of this free-will offering is not only supplying the deficiencies of the saints, but also superabounding through much thanksgiving to God;

Thanks be unto God for His unspeakable gift.

for the weapons of our warfare are not carnal, but mighty to God unto the pulling down of strongholds;

But we are praying unto God, that he may do you no evil, not in order that we may appear approved, but that you may do that which is good, and we may be as disapproved.
