It is vain to try and hide a bad spirit from the eyes of them who are spiritual, for it will show itself in speaking and in writing as well as in all other conduct, it is also useless to make great pretensions when the heart is not right before God, for God looks at the heart, and where the heart is not right the Lord will expose it to the view of the faithful.
Joseph Smith, Jr.A man is saved no faster than he gets knowledge. For if he does not get knowledge, he will be brought into captivity by some evil power in the other world, as evil spirits will have more knowledge, and consequently more power.
Joseph Smith, Jr.
