In a free country, to be a member of a church, it is enough to believe and be baptized. In the Church underground it is not enough to be a member in it. You can be baptized and you can believe, but you will not be a member of the Underground Church unless you know how to suffer. You might have the mightiest faith in the world, but if you are not prepared to suffer, then you will be taken by the police. You will get two slaps and you will declare anything. So the preparation for suffering is one of the essentials in the preparation for underground work.
