Right before his ascension Jesus told the disciples, "But ye shall receive power, after that the Holy Gost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth." (Acts 1:8) What required a dispersion in the New Testament to get the baby Christians off their behinds in Jerusalem and spreading the Gospel to the rest of the world is now seemingly done with the typing of fingers on a keyboard anywhere there is Internet.
Is New Media God's way of helping us fulfill Jesus' prophecy? The missions explosion of the 18th and 19th centuries nearly spread the Gospel to the uttermost reaches of the earth. Yet there are still tribes, tounges, and peoples who have not heard the Good News of Jesus Christ. While it may be easy to post our Christian convictions online and then call to the world, "Come and get it!," there must be people who physically travel to remote places, proclaim Christ, and help the people get copies of the Scriptures in their own language.
Thankfully, online media can help missionaries stay in close contact with their sending organizations to provide prayers, money, and physical resources for the proclamation of Christ. And when the missionaries have trained disciples of the local peoples and packed up to move where God is calling them next, they can in turn stay in close contact with their new brothers and sisters in Christ -- through satellite phones, smart phones, and solar chargers if there are no land lines or power stations. Using a blend of old and new schools, we are within striking distance of being Christ's witnesses unto the uttermost part of the earth.
