'O God' in the Bible

I continually give thanks to God on your behalf, for the favour he has bestowed on you thro' Jesus Christ;

You have already a sufficiency, you already abound, you live like princes in our absence: and would to God you did reign, that we too might have the advantage of your administration.

meat does not recommend us to God: if we eat, we are not the better men; if we don't eat, we are not the worse.

to those who are without the law, as without that law, (not as being under no law to God, but as under the law to Christ) that I might gain those who are without the law.

no, but that what the Gentiles sacrifice, they sacrifice to demons, and not to God: and I would not have you partake of the sacrifices of demons.

Be you yourselves judges: is it decent for a woman to pray to God without a veil?

for he that speaks in an unknown tongue, speaks not to men, but to God: for no man can understand the mysteries he delivers by the spirit.

but if there be no interpreter, let him keep silence in the church; and tacitly address himself to God.

and then will be the end, when he shall deliver up the kingdom to God even the father; after having abolished all rule, and all authority, and power.

but thanks be to God, who has given us the victory, thro' our Lord Jesus Christ.
