God has prepared what we need for cross-cultural interaction. Similar to the commercial climate of the early Roman world, today in the pursuit of the benefits of commerce and tourism many governments and businesses world-wide have cooperated to allow easy and relatively safe travel throughout the world. Travel that used to take weeks or months now takes hours.
God has made available new global communication which ministries can use. With the arrival of the internet, telephone, radio and television, people communicate almost instantaneously between nearly any points on earth. Radio, television, or website-based news carries live coverage to people around the world. A crisis on the other side of the world flashes on the television or computer screen as if it was just down the street.
During the Greco-Roman era, the Jews scattered around the known world to do business and God used many of them to spread His Gospel by taking advantage of their strategic locations. With the increase of open borders and businesses across borders, God is now moving similarly, putting people in strategic locations for His purposes.
