What were workers of miracles?
Why was this group listed after teachers by Paul?
1. The workers of miracles were the apostles, and those on whom they "laid hands" (Acts 6:6, 8:17, 19:6, etc.).
2. Teachers -- preachers or evangelists, are crucial so that people might hear the Word of God.
We might understand that a miracle is an "event that is not explicable by natural or scientific laws and is therefore considered to be the work of a divine agency." Although a secular source, Google Dictionary is as good as any: Miracles occurred as an act of God.
The order of the offices given by Paul is, indeed, interesting. Suppose we break this down to only the first four offices listed:
- Apostles. These were direct witnesses of Christ, and had the power to heal, to prophesy, to teach or evangelize (as did Paul), to perform miracles, to heal, etc. The greatest contribution by the apostles was dissemination of God's Word. There is no greater need than this.
- Prophets. These people proclaimed prophecy not only to the people, but even to the apostles themselves (cf. Acts 21:10, etc.). Today, as the faithful, we are also prophets as we proclaim the Word of God to those who have not heard. However, again, the most important function by any of God's emissaries was to reveal the Gospel, especially in its infancy.
- Teachers. Teaching, evangelizing, or preaching is vital if we are to hear the Word:
Romans 10:17: "So faith comes from hearing, and hearing by the word of Christ" (emphasis added).
This passage indicates that faith in Christ is contingent upon first hearing the Gospel — in the first century, that occurred through the teaching of the apostles (Matthew, John), the and disciples (Mark, Luke, etc.).
- Workers of Miracles. This gift bestowed by the apostles upon the "laying of hands." We learn this, as previously suggested, from the Book of Acts:
Acts 6:5b-6: "They chose Stephen, a man full of faith and of the Holy Spirit, and Philip, Prochorus, Nicanor, Timon, Parmenas and Nicolas, a proselyte from Antioch. And these they brought before the apostles; and after praying, they laid their hands on them" (emphasis added).
While we might think that performing miracles would be at the top of this list, what is paramount to recognize is that to receive salvation, we must hear the Word, believe in Christ, repent of sins, and confess the deity of Christ at baptism. What must follow, of course, is a life of godliness.
The steps to redemption in Christ take precedence over all else, including miracles.
