Thus came the voice of the Son unto me, saying:
After ye have repented of  your sins,
and witnessed unto the Father that
ye are willing to keep my  commandments,
by the baptism of water,
and have received the baptism
of  fire and of the Holy Ghost,
and can speak with a new tongue,
yea, even  with the tongue of angels,
and after this should deny me,
it would have  been better for you
that ye had not known me.
(2 Nephi 31:14)
