While eschatology is important, it is nothing to consume you. It could be argued that by getting you to climb this mountain of prophecy, the devil has effectively removed you from the ranks of able-bodied preachers, in order to do his will.
Jesus spoke of feeding the hungry, giving drink to the thirsty, clothing the naked, befriending the stranger, and visiting the imprisoned. All of these have an esoteric and exoteric meaning, but none has anything to do with end-times theology.
Stephen was stoned knowing nothing of eschatology, James knew only what Christ had told him, the thief on the cross knew only the Gospel, and the Ethiopian Eunich ran off to Africa without a copy of the Books of Revelation, Matthew, or Thessalonians. Each of these men is safely held in the hand of God without the faintest idea of Christ's return.
Revelation contains valuable ministerial information, Dr. John MacArthur calls 2 Thessalonians a Pastoral Epistle instead of an Eschatological Epistle, and all scripture is valuable for doctrine, reproof, correction, and training in righteousness. The value of eschatology is not in a proper understanding of the Gospel or a litmus test for salvation, but a promise and expectation that this present evil age will not last forever. Dr. William Varner states masterfully that prophecy is not given to form a calendar, but to form a character; a character of prayerfulness, watchfulness, honesty, and holiness.
Instead of arguing on which way the Millennial Reign will pan out, it is best to work out your salvation with fear and trembling, then go forth and preach the Gospel to all creation.
Christ is not preparing to say, "Well done, good and faithful servant, you figured out a difficult riddle at the expense of the hungry, thirsty, naked, lonely, and imprisoned."
The servant will be lauded for being good and faithful in delivering the Bread of Life, Living Water, Righteousness, Friendship, and Liberty to the lost and snatching them, in mercy, out of the fire.
Please consider this: eschatology is a fascinating subject, but its bearing on salvation is non-existent, and letting it consume you gives a temporary victory to satan in consuming the efforts of a valuable minister of Christ.
