"And now, verily I say unto you, and this is wisdom, make unto yourselves friends with the mammon of unrighteousness, and they will not destroy you." (D&C 82:22 )
“Our lives have already become jeopardized by revealing the wicked and bloodthirsty purposes of our enemies; and for the future we must cease to do so.
All we have said about them is truth, but it is not always wise to relate all the truth. Even Jesus, the Son of God, had to refrain from doing so, and had to restrain His feelings many times for the safety of Himself and His followers, and had to conceal the righteous purposes of His heart in relation to many things pertaining to His Father’s kingdom.
When still a boy He had all the intelligence necessary to enable Him to rule and govern the kingdom of the Jews, and could reason with the wisest and most profound doctors of law and divinity, and make their theories and practice to appear like folly compared with the wisdom He possessed; but He was a boy only, and lacked physical strength even to defend His own person; and was subject to cold, to hunger and to death.
“So it is with the Church of Jesus Christ of Latter-day Saints; we have the revelation of Jesus, and the knowledge within us is sufficient to organize a righteous government upon the earth, and to give universal peace to all mankind, if they would receive it, but we lack the physical strength, as did our Savior when a child, to defend our principles, and we have a necessity to be afflicted, persecuted and smitten, and to bear it patiently until Jacob is of age, then he will take care of himself.” (Teachings of the Prophet Joseph Smith, Section Six 1843-44 pp 392 - the morning of July 27, 1844)
