I think it's great when people wait til they're "mature" to dedicate themselves to their religion (if their faith requires such a thing). I think a little bit of testing beforehand is a good idea because especially in churches which emphasize emotions over reason, people get caught up in stuff, and then backslide pretty quickly. That not only hurts the person but reflects badly on his/her faith. I find it fascinating that in Judaism (traditionally) a person who approaches a synagogue to convert is refused up to 3 times, to test their conviction. Some people say "Oh how harsh and unwelcoming!" But I bet it keeps out the "religious nuts". At my mosque some of the ladies will work to help anyone convert. They've "converted" about 4 people who have certifiable mental problems. According to Islam, those who are insane or mentally incapable are not accountable to God for their actions. It's an embarrassment for me and my faith, and these people don't even realize they've converted. One lady shows up at the mosque in shorts and a tank top and a bandana tied around her head. Another calls people and asks what religion she is. Another talks about "the blood of christ" at the mosque.
