In March, 1839, while the prophet was imprisoned in Liberty jail he wrote to the church for its instruction and comfort, and in the course of his letter in speaking of the priesthood and the exercise of its powers he remarks: "There are many called but few are chosen. And why are they not chosen? Because their hearts are set so much upon the things of this world, and aspire to the honors of men, that they do not learn this one lesson--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. That they may be conferred upon us," he continues, "it is true; but when we undertake to cover our sins, or to gratify our pride, our vain ambition, or to exercise control, or dominion, or compulsion, upon the souls of the children of men, in any degree of unrighteousness, behold the heavens withdraw themselves; the Spirit of the Lord is grieved; and when it is withdrawn, amen to the priesthood, or the authority of that man. Behold, ere he is aware, he is left unto himself, to kick against the pricks; to persecute the saints, and to fight against God. We have learned by sad experience, that it is the nature and disposition of almost all men, as soon as they get a little authority, as they suppose, they will immediately begin to exercise unrighteous dominion. Hence many are called, but few are chosen. "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; by kindness, and pure knowledge, which shall greatly enlarge the soul without hypocrisy, and without guile, reproving betimes with sharpness, when moved upon by the Holy Ghost, and then showing forth afterwards an increase of love toward him whom thou hast reproved, lest he esteem thee to be his enemy; that he may know that thy faithfulness is stronger than the bands of death."
