'O God' in the Bible

For every high priest that is taken from among men is ordained for men, in things pertaining to God, to offer gifts and sacrifices for sins:

So God, willing very abundantly to show, unto the heirs of promise, the stableness of his counsel; he added an oath,

Wherefore he is able also ever to save them that come unto God by him, seeing he ever liveth, to make intercession for us.

How much more shall the blood of Christ - which through the eternal spirit, offered himself without spot to God - purge your consciences from dead works, for to serve the living God?

Then I said, 'Lo I come.' In the chiefest of the book it is written of me, that I should do thy will, o God."

And then he said, "Lo I am come to do thy will o God." He taketh away the first to establish the latter.

But without faith it is impossible to please him: For he that cometh to God, must believe that God is, and that he is a rewarder of them that seek him.

For by him offer we the sacrifice of praise always to God: that is to say, the fruit of those lips, which confess his name.
