I can say to my brethren and sisters who profess to believe in the Gospel of the Son of God, as it has been revealed to us in these latter days, that we need to pay attention to our faith, and to observe the principles of our religion inviolate, and to live by every word that proceeds out of the mouth of God, or we shall not be prepared to inherit that glory that we anticipate. Is this so? It is, most assuredly.
I know that many Latter-day Saints think when they have obeyed the Gospel, made a sacrifice in forsaking their homes, perhaps their parents, husbands, wives, children, farms, native lands, or other things held dear, that the work is done; but it is only just commenced. The work of purifying ourselves and preparing to build up the Zion of God on this continent has only just begun with us when we have got as far as that.
