It's all in the emphasis of a particular word:
How can we know there is a God?
How can we know there is a God?
How can we know there is a God?
The last is the most important: personal experience. However, it's also the most unprovable. How can one human, even the most prominent of the Biblical prophets, or even Jesus Christ himself, prove that he had an interaction with God? If he can't prove it, then the experience, though valid in its own right, remains strictly a personal one, and provides no basis as proof to another human being.
defd, are you asserting that you have had such a personal experience with God?
If not, then you are simply spouting the assertions of others.
If so, then please explain that experience, in terms that the rest of us mere mortals (no offense intended) can apprehend.
