What do you think 'belief in God' means, and entails?
Let me just jump in here and try to short-cut the inevitable lengthy discussion that Jan wants you to embark on.
In common usage, a person is said to "believe in God" if he or she believes that God exists as a real being in the world, and not just as a fantasy or story.
In Jan Ardena's usage, as I understand it, a person only "believes in God" if he or she wholeheartedly gives himself or herself over to the worship of Jan's particular conception of God. Such a person knows instinctively that God is real because he or she feels it in his or her whole being. The "real world" is then to be viewed through the lens of this "belief in God", such that everything that exists in the world is then seen by the believer as evidence of God.
Thus, for Jan, the Believer in God needs no actual evidence of God. His or her own conviction is sufficient in itself. He or she is, moreover, then free to adopt particular "scriptures" and to interpret them in such a way as to support his or her pre-formed conviction in the "reality" of God.
As you can see, the meanings of the phrases "belief in God" and "evidence" are redefined by Jan to form a closed loop. The "belief in God" is all the "evidence" that is needed, and everything that exists is part of the "evidence" for the belief.
It is a fairly pointless exercise to discuss matters of belief and evidence with Jan, because what counts as "evidence" in science (for example) is only a tiny subset of what counts as evidence in Jan's mindset. The starting point is not the evidence, but the Belief in God. Evidence is actually beside the point, from this point of view.
Jan will tell you that you only need to look at things with your head tilted at the right angle to Believe in God. You just have to be open to accepting God - which means, essentially, being open to believing in the absence of real evidence.
