At the Kingdom Hall, which resembles not so much as church as a small lecture room, the prospect hears a Witness discuss a few verses can be conveyed to non-Witnesses. The prospect gets still more of this if he proceeds to the next step, which consists of going to meetings on Wednesday or Thursday nights. At those meetings Witnesses trade stories, explaining how they've done that week in going door to door, giving advice to one another, figuring out better ways to get the message across, logging their hours. If the prospect goes through all these steps, he's ready for admission to the sect. That involves baptism by immersion and agreeing to work actively as a missionary.
Many missionaries take only part-time jobs so they can devote more time to their religious work.
It's not uncommon for a Witness to log more than 150 hours monthly in house calls. Although not every Witness can put in so many hours, every Witness is expected to do hat he can by way of missionary work. The Witnesses believe, following Luther's teaching on the universal priesthood of believers, that each of them is a minister, and they act on this belief. There is no separate, ordained ministry as is found in Protestant churches. Their main task is to enlarge the rolls.
