Knowing the mysteries of God

Ammon taught that the natural man cannot know the mysteries of God.
Instead a person must exercise faith in Christ, repent and do good,
praying continually. (http://scriptures.lds.org/en/alma/26)

21 And now behold, my brethren, what natural man is there that
knoweth these things? I say unto you, there is none that knoweth these
things, save it be the penitent.
22 Yea, he that repenteth and exerciseth faith, and bringeth forth
good works, and prayeth continually without ceasing—unto such it is
given to know the mysteries of God; yea, unto such it shall be given
to reveal things which never have been revealed; yea, and it shall be
given unto such to bring thousands of souls to repentance, even as it
has been given unto us to bring these our brethren to repentance.
