All down the ages God has searched for man in the open air. The first mention of church houses is found in the writings of Tertullian at the end of the second century. Justin Martyr was converted by the testimony of an old man preaching in the open air. Saint Mary’s Church in Whitechapel, London, has a pulpit built in the corner on the outside, from which the preacher reaches more people than he can induce to come within. A few children of the church members join, as a matter of course, but those that come in by regeneration are nearly all reached in the open air. Jesus was crucified in the open air, and from the top of Olivet he ascended in the open air. In like manner he shall return with the glory of his Father and the angels in the open air.
