Read it through once

During a persecution of the Christians, the aged John of Patmos has been secretly conveyed, by some faithful disciples, to a cave in the desert, where he is dying. Revived temporarily by the tender ministrations of his disciples, he is enabled to tell over his past labors in the service of his beloved Master, to refute the Antichrist already in the world, and to answer the questions which, with his far-reaching spiritual vision, he foresees will be raised in regard to Christ’s nature, life, doctrine, and miracles, as recorded in the Gospel he has written. These services he feels to be due from him, in his dying hour, as the sole survivor of Christ’s apostles and intimate companions.
