I like the scripture in the Doctrine and Covenants, Section 35 verse 24;

"Keep all the commandments and covenants by which ye are bound; and I will cause the heavens to shake for your good, and Satan shall tremble and Zion shall rejoice upon the hills and flourish; and Israel shall be saved in mine own  due time; and by the keys which I have given shall they be led, and no more be confounded at all."
