'O God' in the Bible

I give praise to God that not one of you had baptism from me, but Crispus and Gaius;

So, then, as to the question of taking food offered to images, we are certain that an image is nothing in the world, and that there is no God but one.

To those without the law I was as one without the law, not as being without law to God, but as under law to Christ, so that I might give the good news to those without the law.

What I say is that the things offered by the Gentiles are offered to evil spirits and not to God; and it is not my desire for you to have any part with evil spirits.

But if I give praise to God for the food which I take, let no man say evil of me for that reason.

For he who makes use of tongues is not talking to men but to God; because no one has the sense of what he is saying; but in the Spirit he is talking of secret things.

I give praise to God that I am able to make use of tongues more than you all:

The secrets of his heart are made clear; and he will go down on his face and give worship to God, saying that God is truly among you.

But if there is no one to give the sense, let him keep quiet in the church; and let his words be to himself and to God.

Then comes the end, when he will give up the kingdom to God, even the Father; when he will have put an end to all rule and to all authority and power.

But praise be to God who gives us strength to overcome through our Lord Jesus Christ.
