Everywhere I go, I hear about it. More and more people are dedicated to it.
Most churches have groups that regularly do it.
Many people have seen it as their primary calling as a disciple. If you peruse your local Christian bookstore, or look at books online, you will find a large number of titles about it. It's no secret, we've just awakened it from hibernation and retrieved it from eclipse. This great blessing is prayer. God longs for us to pray for our neighbors and their hearts to be open to the Gospel.
