Dima, if the problem stems from:
He had a lot a lot of bad experiences with Christians and the church, pretty much wherever he went.
The WotM good person test won't help matters. He already KNEW he was a bad person. He just discovered that many of those in the churches he attended weren't any better.
The solution is in convincing him that he needs to be the "Good Christian" and thus the example to all the "Bad Christians," that the actions of other Christians should not prevent him from loving and worshipping God, that Jesus loves him... and would still die for just him on a cross, that his faith isn't a waste just because others are wasting theirs.
WotM is an ice breaker. It's a conversation opener. It's to get the person you are talking with to open their minds to the spiritual. Beyond that... it's up to God and you as to what happens. This guy is beyond the ice breaker.
