Strengthen the Hands of Your Fellow Beings - Brigham Young

If you feel evil, keep it to yourselves until you overcome that evil principle. This is what I call resisting the devil, and he flees from me.... When you are influenced by the Spirit of holiness and purity, let your light shine; but if you are tried and tempted and buffeted by Satan, keep your thoughts to yourselves- keep your mouths closed; for speaking produces fruit, either of a good or evil character...

You frequently hear brethren and sisters say that they feel so tried and tempted, and have so many cares, and are so buffeted, that they must give vent to their feelings; and they yield to temptation, and deal our their unpleasant sensations to their families and neighbors. Make up your minds thoroughly, once and for all, that if we have trials, the Lord has suffered them to be brought upon us, and he will give us grace to bear them....

But if we have light or intelligence- that which will do good, we will impart it.... Let that be the determination of individual, for spirit begets spirit-likeness; feelings beget their likeness... If then we give vent to all our bad feelings disagreeable sensations, how quickly we beget the same in others, and load each other down with our troubles, and become sunk in darkness and despair!...

In all your social communications... let all the dark, discontented, murmuring, unhappy, miserable feelings- all the evil fruit of the mind, fall from the tree in silence and unnoticed; and so let it perish, without taking it up to present to your neighbors. But when you have joy and happiness, light and intelligence, truth and virtue, offer that fruit abundantly to your neighbors, and it will do them good, and so strengthen the hands of your fellow beings.
