While all Christians are to evangelize and teach to some degree depending upon their talents and opportunities, God also recognized that some congregations would need individuals to work among them on a daily basis, preaching the whole counsel of God both to them and to the lost of the world (Acts 20:18-21, 26-27, 31-32; 1 Timothy 4:6, 11, 13, 15-16; Titus 2:1, 15 ) and joining with the pastors and other teachers of the congregation to use the doctrine of the apostles and prophets which is the New Testament to “equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood” (Ephesians 4:11-12).
