The book of Revelation as the last of the books in the Bible and of the New Testament is the only major prophetic book of the New Testament. In this intense and interesting book the curtain is lifted and the future is revealed.
The main purpose of the book of Revelation is to introduce the Second Coming of Jesus Christ as a comforting message to the Church. Revelation deals with the end-times and with end-time events. Consequently we may speak of the eschatological expectations of the child of God.
Eschatology is the doctrine of the end-times regarding the final events in this world; of the return of the Lord Jesus Christ to this world; of the resurrection of the dead, and of the final judgment.
