Whatever Happened to the Twelve Apostles?

Have you ever wondered what the TWELVE APOSTLES did once the excitement of the Day of Pentecost died down? In the early chapters of Acts it seems as if Peter and John were the only ones doing anything much for the Lord.Yet in the book of Revelation John saw the names of all twelve apostles on the foundations of the New Jerusalem. And Jesus had promised that in His future kingdom the apostles would sit on twelve thrones judging the twelve tribes of Israel. Surely these men must have done something outstanding to warrant such great honours. From early church writings we are able to form a reasonably accurate picture of where each apostle went to preach this new gospel that Jesus had entrusted to them. Their devotion was such that, with the exception of John, it seems each died a martyr for the faith he had so boldly proclaimed.
