D&C 105

As directed by the Lord, a group of the faithful known as Zions Camp, having traveled a great distance and having endured great affliction for the purpose to redeem the land of Zion. As Zions Camp was camped on Fishing River a short distance from their final destination the Lord tells the camp -

"...I say unto you who have assembled yourselves together that you may learn my will concerning the redemption of mine afflicted people—" (Doctrine and Covenants Section 105:1)

And His will was that -

"...it is expedient in me that mine elders should wait for a little season for the redemption of Zion—" (Doctrine and Covenants Section 105:9)

I've thought how the men must have felt after all they had endured. There must have been - "why"s and "you have got to be kidding". But the Lord then explains. At first the voice may sound like a lecturing voice, but since I have come to feel a very compassionate, loving voice -

"...were it not for the transgressions of my people, speaking concerning the church and not individuals, they might have been redeemed even now.
3 But behold, they have not learned to be obedient to the things which I required at their hands, but are full of all manner of evil, and do not impart of their substance, as becometh saints, to the poor and afflicted among them;
4 And are not united according to the union

The people were not ready or properly prepared to be redeemed -

"...Zion cannot be built up unless it is by the principles of the law of the celestial kingdom; otherwise I cannot receive her unto myself." (Doctrine and Covenants Section 105:5)

I'm sure many of the saints thought that they just needed to show up and all would be as Zion. But the Lord explained -

"...my people must needs be chastened until they learn obedience, if it must needs be, by the things which they suffer." (Doctrine and Covenants Section 105:6)

And then He teaches the process of acquiring Zion -

"Therefore, in consequence of the transgressions of my people, it is expedient in me that mine elders should wait for a little season for the redemption of Zion—
10 That they themselves may be prepared, and that my people may be taught more perfectly, and have experience, and know more perfectly concerning their duty, and the things which I require at their hands." (Doctrine and Covenants Section 105:9 - 10)

And even -

"...this cannot be brought to pass until mine elders are endowed with power from on high.
12 For behold, I have prepared a great endowment and blessing to be poured out upon them, inasmuch as they are faithful and continue in humility before me.
13 Therefore it is expedient in me that mine elders should wait for a little season, for the redemption of Zion." (Doctrine and Covenants Section 105:11 - 13)

For Zion to be redeemed, it must first become "the pure in heart". In conclusion, the Lord teaches -

"There has been a day of calling, but the time has come for a day of choosing; and let those be chosen that are worthy." (Doctrine and Covenants Section 105:35)

And those that choose righteously, that are proven worthy become chosen and -

"And it shall be manifest unto my servant, by the voice of the Spirit, those that are chosen; and they shall be sanctified..." (Doctrine and Covenants Section 105:36)
