'O God' in the Bible

We give thanks to God always for you all, making mention of you at our prayers,

for they themselves relate concerning us what entering in we had to you, and how ye turned to God from idols to serve a living and true God,

And for this cause we also give thanks to God unceasingly that, having received the word of the report of God by us, ye accepted, not men's word, but, even as it is truly, God's word, which also works in you who believe.

For what thanksgiving can we render to God for you, for all the joy wherewith we rejoice on account of you before our God,

For if we believe that Jesus has died and has risen again, so also God will bring with him those who have fallen asleep through Jesus.
