Acts 1:8 (KJV)
But ye shall receive power, after that the Holy Ghost 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.
It’s no wonder that Christianity spread across the world so quickly. It’s exactly what they were supposed to do then and most believe we should be doing the same thing today, spreading the Gospel to everyone on earth.
