The word apostle means, “one sent forth” in the Greek "apo" = from "stello" = to send. An apostle is sent forth by GOD to minister with GOD given authority. They are pioneers who establish churches and lays foundational truth(Ephesians 2:20). Apostles could be called “spiritual builders” (1Corinthians 3:10). They have oversight of the body (1Corinthians 4:15).
The ministry of Apostleship is an area much in need of restoration to the Church by the Holy Spirit. Most people think that the original twelve disciples are the only real apostles. Although they hold a special place as the original apostles, the Bible mentions many other apostles including Matthias (Acts 1:26), Paul (Acts 14:1, 4,14), Titus (2 Corinthians 8:23), Epaphroditus (Philippians 2:25), Silas and Timothy (1 Thessalonians 1:1, 2:6). Also Andronicus and Junia, listed in Romans 16:7 were possibly Apostles. This shows that there were apostles after the original twelve.
The first and foremost apostle is Jesus Christ (Hebrews 3:1). He was sent forth from heaven on a divine mission for the Father. Jesus chose the original apostles (Luke 6:12-13), trained them (Mark 3:14-15) and commissioned them (Matthew 28:19-20; Acts 1:1-8). The book of Acts reveals how the apostolic ministry functioned in theearly Church. As the apostles traveled and evangelized, they saw a need for permanent leadership in the churches they established. As a result, they ordained men to be elders, pastors and overseers in each five-fold ministry, including apostles.
The Bible does not teach that apostleship was to cease. Rather, the Word teaches that apostles are much needed in the body of Christ. They are sent to capture, recapture influence and/or control in GOD assigned areas while organizing, setting order or restructuring the body of Christ. The ministry of an Apostle is marked by signs, wonders and miracles.
