When I was in our College/Career youth group at a smaller Scottsdale Bible Church, we had some Bahai visitors. They asked us to come and share our beliefs at their church. We did this, and I was afraid at first, but our leader gave a full and lengthy presentation of Jesus!
They did not say much or anything at all to teach us their doctrine. They just listened. I praise God for giving us this opportunity to witness to this cult group.
