Good post. One has to wonder what all those missionaries were doing since Pentecost. The Great Commission was a directive from Jesus Christ to go out and preach the Gospel to all nations. I have to say serving in Arab Muslim countries over the past 11 years there may not be missionaries screaming on the street corners often but you cannot go two blocks without an internet tea house and every roof has a satellite dish. The Gospel is reaching the four corners of the earth.
I have enjoyed your posts on this thread, redleghunter. As you said, we cannot understate the power of the Holy Spirit to reach whom He wills.
