Again... I would have to disagree... Our church is filled with changed humanity. As He created people with free will, it is up to each individual to decide whether or not they want to be part of a changed humanity.The fact that he failed to successfully change humanity by wiping virtually everyone off the face of the earth is no opinion. Biblewise that's a fact. And to me, failure is counter to any definition of omnipotence I've ever seen.

Additionally, it was about getting Jesus into the earth (by Christian understanding) to be the change agent. He accomplished that too.

I would disagree on your interpretation of omnipotence. An omnipotent God can create individuality and free will because He is omnipotent. In as much as He isn't finished yet, your judgment on a work in progress is simply your viewpoint (as if you were omnipotently wise in your judgment). People don't usually judge a car that is being manufactured but rather judge the finished product.And I recognize that, but I would ask those people if his failure, as I've pointed out, is an act of an omnipotent god. Wouldn't an all-powerful god have succeeded? And in turn wouldn't any such a failure be a mark of incompetence?
God was unable to successfully change humanity, and that he sought to do so is evident in having saved Noah and his family.in·com·pe·tence

As it was so fitly said by a famous believer "The good work that He has begun, He is well able to complete it".
As an omnipotent God, your timeframe is irrelevant because He IS omnipotent to decide the timeframe of completion.
So I would still disagree with your logic and interpretation of the facts at hand.
