'O God' in the Bible

But food does not commend us to God; for neither if we eat not are we worse, nor if we eat are we better.

to those without law, as without law, being not without law to God, but with law to Christ, that I might gain those without law;

But what the gentiles sacrifice, they sacrifice to demons, and not to God; and I do not wish you to be partakers with demons.

Judge of yourselves; is it becoming that a woman should pray to God unveiled?

For he that speaks with a tongue speaks not to men but to God; for no one understands him, but in spirit he speaks mysteries;

and if there is no interpreter, let him be silent in the assembly, and let him speak to himself and to God.

and we are found also false witnesses of God, because we testified in regard to God that he raised up Christ, whom he raised not up if indeed the dead are not raised.

but thanks be to God who gives us the victory through our Lord Jesus Christ.
