- Mosiah 8:16 -18…16 And Ammon said that a seer is a revelator and a prophet also; and a gift which is greater can no man have, except he should possess the power of God, which no man can; yet a man may have great power given him from God. 17 But a seer can know of things which are past, and also of things which are to come, and by them shall all things be revealed, or, rather, shall secret things be made manifest, and hidden things shall come to light, and things which are not known shall be made known by them, and also things shall be made known by them which otherwise could not be known. 18 Thus God has provided a means that man, through faith, might work mighty miracles; therefore he becometh a great benefit to his fellow beings.
