“Blessed are all the pure in heart.”

3 Nephi 12:8

8 And blessed are all the pure in heart, for they shall see God.

President Harold B. Lee said:

“Only if you are the pure in heart will you see God, and also in a lesser degree will you be able to see the ‘God’ or good in man and love him because of the goodness you see in him. Mark well that person who criticizes and maligns the man of God or the Lord’s anointed leaders in His Church. Such a one speaks from an impure heart.”
