Cry unto Him for Mercy for He is Mighty to Save

Amulek teaches that part of exercising faith unto repentance is to call upon God for mercy.

“…May God grant unto you, my brethren, that ye may begin to exercise your faith unto repentance, that ye begin to call upon his holy name, that he would have mercy upon you; Yea, cry unto him for mercy for he is mighty to save.” (Alma 34:17-18)
