I became aware that if you're really going to test the reality of a church you had to test it on its own ground and the church, as a ground, demands that we approach it by prayer and I simply decided to meet that need of prayer as an approach to the church and simply to ask “show me”, is it true? Just show me. And the evidence came unexpectedly and from many quarters and unmistakeably and I think that, it might be a rather interesting scientific experiment for any non-believers, they're called, to simply get down on his knees for a few hours every week and demand that he be shown the reality of this unknown thing and it doesn't depend, anybody will soon discover, it does not depend upon concepts, theories, ideas, it is a thing with a life that is available to all who want to share in that life but it must be demanded. Seek and you shall find, knock and it shall be opened unto you, but you have to knock and you have to knock pretty hard.
