D&C 67
I found it instructive this morning as I read -
"Ye endeavored to believe that ye should receive the blessing which was offered unto you; but behold, verily I say unto you there were fears in your hearts, and verily this is the reason that ye did not receive." (Doctrine and Covenants 67:3)
In my mind, these saints desired a blessing (which the Lord did not tell us what is was), and because they "feared in their hearts" they did not receive it. How many of us have been given callings and prayed sincerely for help, but our heart was full of fear?
