At the end of the New Testament era primary revelation ceased when the apostles completed their task of preserving, communicating and explaining the teachings of Christ. The New Testament is the end product of their work. In second Corinthians chapter 14, Paul the apostle encourages his readers to seek this gift rather than the gift of tongues. The modern ministry of preaching, forcefully proclaiming the Kingdom through the teachings of Christ, is probably very close to the New Testament ministry of prophecy. God's call to the ministry is a mysterious business.
Some pastors seem to doubt their call, yet their call is patently obvious to everyone else.
Other's assure us of their call, but their ministry seems to deny the presence of the divine. Yet apart from the ordained ministry there is a sense where we are all called, all called to serve as prophets of the Lord. We are all called to minister the gospel to God's broken world. Jeremiah's call was clear and precise and can aid us in understanding our call. We are called to make known the gospel of Christ.
