And now I say unto you that the good shepherd doth call after you; and if you will hearken unto his voice he will bring you into his fold, and ye are his sheep; and he commandeth you that ye suffer no ravenous wolf to enter among you, that ye may not be destroyed.Alma 6
The children of God were commanded that they should gather themselves together oft, and join in fasting and mighty prayer in behalf of the welfare of the souls of those who knew not God.
