Matthew 24:14 - And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
Now that you have mentioned technology Eddie, this verse make even more sense. Since The Gospel can now be reached throughout the utmost parts of the World through media and via internet, it can easily be preached unto all the world.
And since the servants of God are ministering throughout the world and Christianity is growing, i can pretty much come to the conclusion that, it is right at the doors.
