By stating this as He did, He was admonishing the apostles not to become fixated on the fulfillment of prophecies but to remain focused on preaching the gospel. For that end, He will give them power. He wanted them to concentrate on the job at hand. The Great Commission, though, is now not only global geographically, but in terms of time, it is also totally open-ended. Moreover, no God-given, intermediate goals are in sight. The church today must take its cue from the way Jesus Christ handled the situation with the first-century church.
What began at this critical time in history was that God's global re-educational institution—the church, the Israel of God (Galatians 6:16)—was taking its first steps in teaching everyone worldwide how they should live. The church Jesus founded was beginning to preach the gospel from this starting point in both place and time, an activity that will eventually reach every person who has ever lived. In other words, beginning then, the church became the focal point of God's reeducation program.
Jesus was transitioning His work from what was merely an Old Covenant, Israelite, religious organization—of interest to relatively few outside Israel—to an educational organization that in terms of time will span thousands of years and become of intense interest to everybody. In directing the apostles in this way, Christ wanted His church to inaugurate this work yet keep it contained within the parameters He and the Father set as the church progressively developed at the speed it could handle effectively.
It may be helpful to remember that the earliest brethren in the church had to face their public responsibilities to Jesus without the help of what is now roughly one-third of the Bible—the New Testament. Scholars posit that the gospel of Mark was written first, followed by Matthew, Luke, and John. The earliest possible date even for Mark appears to be around AD 40, but some place it as late as AD 65.
In addition, it appears that I Thessalonians was the first of the epistles circulated within the church, but the apostle Paul did not write it until approximately AD 50. How many new converts even possessed their own copy of an Old Testament in their homes? Very few. There were no printing presses, no radio and television broadcasting, and no computers. To purchase a copy of the Old Testament would have cost a working man an entire year of wages! Was there a reference work similar to a Strong's Concordance of the Bible for somewhat more serious researching? Of course not.
Looking back in this way confirms that the early preaching of the gospel was a work of faith, highly dependent on the apostles' spiritual relationship with Jesus Christ. What likely sustained the members' spirituality was the spoken word delivered to people who listened carefully and concentrated with great intensity. These “pioneers” were remarkable, spiritually-minded people.
The Jewish religious leadership perceived that the apostles lacked preparation for such a huge responsibility (Acts 4:13). This terminology does not mean that the apostles had received no education at all. The wording expresses that the Jews considered the apostles to be common men who lacked the educational advantages they would have received had they been prepared for such public evangelism in rabbinical schools. However, recall that Mark 3:13-14 establishes that Jesus chose and appointed those He specifically wanted as apostles so that they might be with Him (that is, to witness His teaching and activities), and He sent them out to preach. Undoubtedly, He was searching for budding characteristics that He could build upon. He prepared them well to carry out their responsibilities.
