The TRUTH is the Faith OF GOD. That is If you want to know Truth.
Are you suggesting that God has Faith? Since faith is the evidence of things not seen, is there something in the universe that God has not seen?
The term "Faith of God" is used by such aberrant Word of Faith preachers as Kenneth Copeland. They somehow take that phrase to claim that they have not their own faith (which was given to them in measure by God) but the ACTUAL FAITH OF GOD, which of course gives them the power to do all kinds of miracles, such as squeezing money out of the wallets of poor old ladies.
So I don't know what you think the Faith OF God is, but if it refers to obtaining something more than the mere measure of faith given to believers as noted in Romans 12:3 then I would have to say that your belief if dangerous to your spiritual well being.
My point, however is not whether or not the word is OF or IN, my point is that in order to come to some conclusion one way or the other, you have to rely on something other than the scripture itself. Clearly CB misquoted the Scripture when he underscored a word that is not even in the text. He interpreted the verse to suit his theology (whatever that is).
In other words, he did exactly what he accuses everyone else of doing. But will he admit that he was wrong?
I don't think so. That would require a measure of humility.
