Thy mind, O man! if thou wilt lead a soul unto salvation, must stretch as high as the utmost heavens, and search into and contemplate the darkest abyss, and the broad expanse of eternity—thou must commune with God. How much more dignified and noble are the thoughts of God, than the vain imaginations of the human heart! None but fools will trifle with the souls of men.

How vain and trifling have been our spirits, our conferences, our councils, our meetings, our private as well as public conversations—too low, too mean, too vulgar, too condescending for the dignified characters of the called and chosen of God, according to the purposes of His will, from before the foundation of the world! We are called to hold the keys of the mysteries of those things that have been kept hid from the foundation of the world until now. TPJS pg. 137

D&C 84: 54-57

“And your minds in times past have been darkened because of unbelief, and because you have treated lightly the things you have received—

Which vanity and unbelief have brought the whole church under condemnation.

And this condemnation resteth upon the children of Zion, even all.

And they shall remain under this condemnation until they repent and remember the new covenant, even the Book of Mormon and the former commandments which I have given them, not only to say, but to do according to that which I have written—“

II Nephi 9:41

“O then, my beloved brethren, come unto the Lord, the Holy One. Remember that his paths are righteous. Behold, the way for man is narrow, but it lieth in a straight course before him, and the keeper of the gate is the Holy One of Israel; and he employeth no servant there; and there is none other way save it be by the gate; for he cannot be deceived, for the Lord God is his name.”

Mosiah 3:17

“And moreover, I say unto you, that there shall be no other name given nor any other way nor means whereby salvation can come unto the children of men, only in and through the name of Christ, the Lord Omnipotent.”

II Nephi 26:9

“And when they shall have received this, which is expedient that they should have first, to try their faith, and if it shall so be that they shall believe these things then shall the greater things be made manifest unto them.”

Helaman 3:35

“Nevertheless they did fast and pray oft, and did wax stronger and stronger in their humility, and firmer and firmer in the faith of Christ, unto the filling their souls with joy and consolation, yea, even to the purifying and the sanctification of their hearts, which sanctification cometh because of their yielding their hearts unto God.”

Moroni 6: 1-6

“And now I speak concerning baptism. Behold, elders, priests, and teachers were baptized; and they were not baptized save they brought forth fruit meet that they were worthy of it.

Neither did they receive any unto baptism save they came forth with a broken heart and a contrite spirit, and witnessed unto the church that they truly repented of all their sins.

And none were received unto baptism save they took upon them the name of Christ, having a determination to serve him to the end.

And after they had been received unto baptism, and were wrought upon and cleansed by the power of the Holy Ghost, they were numbered among the people of the church of Christ; and their names were taken, that they might be remembered and nourished by the good word of God, to keep them in the right way, to keep them continually watchful unto prayer, relying alone upon the merits of Christ, who was the author and the finisher of their faith.

And the church did meet together oft, to fast and to pray, and to speak one with another concerning the welfare of their souls.

And they did meet together oft to partake of bread and wine, in remembrance of the Lord Jesus.”

Helaman 5:12

“And now, my sons, remember, remember that it is upon the rock of our Redeemer, who is Christ, the Son of God, that ye must build your foundation; that when the devil shall send forth his mighty winds, yea, his shafts in the whirlwind, yea, when all his hail and his mighty storm shall beat upon you, it shall have no power over you to drag you down to the gulf of misery and endless wo, because of the rock upon which ye are built, which is a sure foundation, a foundation whereon if men build they cannot fall.”

Mosiah 16:13

“And now, ought ye not to tremble and repent of your sins, and remember that only in and through Christ ye can be saved?”
