The book of Acts is a descriptive history of what happened after the ascension of Jesus Christ. When Jesus Christ walked the face of the earth he was involved with Israel. What would his disciples do after he left? He prepared them:
Acts 1:8 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.
Their lives were going to extend farther geographically and culturally. They would receive from God spiritual ability to reach out far beyond the boundaries of Judaism. Every person who believed, believes or will eventually believe would be strengthened by the spirit of God within to carry it out.
1 Corinthians 2:7-8 But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:Which none of the princes (spiritual opposition) of this world knew: for had they known it, they would not have crucified the Lord of glory.
Jesus Christ could only be in one place at one time. After the day of Pentecost, people with 'Christ in' could be anywhere! It started out in Jerusalem then Samaria and Judea and later, we find centers of outreach in Antioch, Asia Minor, Europe and eventually Rome. What does that mean for us today? Rome was not the uttermost part of the earth! Jesus Christ used a truly inspiring phrase in Acts 1:8: 'the uttermost part of the earth'! That is us today in ways that could hardly be imaginable in the New Testament time. They didn't have airplanes, buses or trains then. There were no cell phones (let alone telephones), printing presses, tv, radio, blogs, facebook, skype and whatever is coming next!
Blogger has a new data map that shows in what places someone has read your blog. I looked at my data map and was amazed. Here's a list: United Kingdom, Brazil, Japan, Poland, Ukraine, Finland, Taiwan, Burundi, Canada, Vietnam and the United States. (Burundi? I had to look this one up. It is in the middle of Africa!) On another list the Philippines, Australia, France, UAE, Latvia, Morocco and Russia showed up! I'm not sure how far uttermost is, but I guess when I get one from Antarctica, that will be close to uttermost. Who would have guessed it back in the first century?
