One of the biggest accomplishments of the Roman Empire was its very travelable roads. Thus the expression, "All roads lead to Rome." Conversely, all of them also led away from Rome. Originally constructed to facilitate Roman conquest, roads were the providential infrastructure that allowed the gospel of Jesus Christ to be propagated throughout Europe and Asia Minor.
Today's internet superhighway, laid down for purposes other than the sharing the gospel, is having the same effect. Social networking pages, websites like Chalcedon's that promote dominion-oriented Biblical worldviews, and live chat sites shrink the globe and allow the people of God to travel while remaining physically in one area.
The implications of this are huge, if we put on the glasses of Scripture to see what a blessing these technologies can be as we further the Kingdom of God. The structure is there; it is our calling to make use of the gifts and talents we've been given and adapt them in our time to make disciples of all nations.
If you don't know how to use a computer, figure it out or get someone to help you! If you email friends and family regularly, be sure to attach some sound Biblical reading material for them to consider. When sharing on networking sites, boldly proclaim your point of view. We have a means by which to exercise our dominion mandate in ways that were unimaginable just twenty years ago.
So, maybe it's time for you to hit the road!
