By the manifestation of the Spirit of God

1. Alma 5: 47
     47 And moreover, I say unto you that it has thus been revealed unto me, that the words which have been spoken by our fathers are true, even so according to the spirit of prophecy which is in me, which is also by the manifestation of the Spirit of God.
2. Moro. 10: 8
     8 And again, I exhort you, my brethren, that ye deny not the ^agifts of God, for they are many; and they come from the same God. And there are ^bdifferent ways that these gifts are administered; but it is the same God who worketh all in all; and they are given by the manifestations of the ^cSpirit of God unto men, to profit them.
