The Fourth Article of Faith states, "We believe that the first principles and ordinances of the Gospel are: first, Faith in the Lord Jesus Christ; second, Repentance; third, Baptism by immersion for the remission of sins; fourth, Laying on of hands for the gift of the Holy Ghost."1 I don't think that it is any coincidence that faith is first on the list.
I like to associate the word trust with the faith. We must have trust in Heavenly Father and Jesus Christ. We must have trust in Christ's Atonement. We must have trust that we will be blessed for being obedient to the commandments.
