D&C 121:36,41-42

D&C 121:36,41-42
 36 That the rights of the priesthood are inseparably connected with the powers of heaven, and that the powers of heaven cannot be controlled nor handled only upon the principles of righteousness.
  41 No power or influence can or ought to be maintained by virtue of the priesthood, only by persuasion, by long-suffering, by gentleness and meekness, and by love unfeigned;
 42 By kindness, and pure knowledge, which shall greatly enlarge the soul without hypocrisy, and without guile—

Sonnet 821 D&C 121:36,41-42

We see the awful power of brute force
The crushing strength of anger, pride and guile
The sharpness of deceit without remorse
Persuading by the preaching of revile.

Though none of this connects with heaven's power
On earth it has a fearful savage way
And tempts the weak and greedy hour by hour
To rule through aggression day by day.

The currencies of kindness and of love
Of patience and of meekness and increase
Of gentleness and yearnings for above
Are not enough alone to purchase peace.

But when combined with priesthood power's might
They'll vanquish earthly evil's awful blight.
