Dispensational, pretribulationists believe that the New Testament teaches that the current Church Age is unique when contrasted with previous and future dispensations. We believe that the church was always a part of God’s eternal plan or decree, but that it was a mystery, not revealed until New Testament times. Such New Testament uniqueness is one of the major reasons that support the rapture of the body of Christ at the end of this age, before the beginning of the 70th week of Daniel. Why do we believe that this is the New Testament teaching?
