With most of these nations closed, how do we now reach them? In the past, we have concluded that closed doors meant no missionary activity. When doors are closed, Paul's solution was simple, "Pray that a door might be opened for me to preach the gospel!" (Col. 4:2). What about prayer? What about the simple and pure power of incense? Hudson Taylor used to say that you must "go forward on your knees."
Is prayer only to aid our missionary activity, or is prayer a form of missionary activity in itself? Is there, by prayer, a way in which intercessors extend themselves into taboo areas? Does God, through the mystery of prayer, invade the space behind closed doors and hearts, and manifest himself in ways that prepare people, if not peoples, for the preaching of the gospel?
