15 Behold, when ye shall rend that veil of unbelief which doth cause you to remain in your awful state of wickedness, and hardness of heart, and blindness of mind, then shall the great and marvelous things which have been hid up from the foundation of the world from you—yea, when ye shall call upon the Father in my name, with a broken heart and a contrite spirit, then shall ye know that the Father hath remembered the covenant which he made unto your fathers, O house of Israel.
16 And then shall my revelations which I have caused to be written by my servant John be unfolded in the eyes of all the people. Remember, when ye see these things, ye shall know that the time is at hand that they shall be made manifest in very deed.
17 Therefore, when ye shall receive this record ye may know that the work of the Father has commenced upon all the face of the land.
18 Therefore, repent all ye ends of the earth, and come unto me, and believe in my gospel, and be baptized in my name; for he that believeth and is baptized shall be saved; but he that believeth not shall be damned; and signs shall follow them that believe in my name.
19 And blessed is he that is found faithful unto my name at the last day, for he shall be lifted up to dwell in the kingdom prepared for him from the foundation of the world. And behold it is I that hath spoken it. Amen.
