3 And thus saith the Lord your God, if you will receive wisdom here is wisdom. Behold, the place which is now called Independence is the center place; and a spot for the temple is lying westward, upon a lot which is not far from the courthouse.
(D&C 57:3)

21 Until the day cometh when there is found no more room for them; and then I have other places which I will appoint unto them, and they shall be called stakes, for the curtains or the strength of Zion.
(D&C 101:21)

I think we are not justified in anticipating the privilege of returning to build up the center stake of Zion, until we shall have shown obedience to the law of consecration. One thing, however, is certain, we shall not be permitted to enter the land from whence we were expelled, till our hearts are prepared to honor this law, and we become sanctified through the practice of the truth. (Lorenzo Snow, JD, 16:276)

Remarks have been made as to our staying here. I will tell you how long we shall stay here. If we live our religion, we shall stay here in these mountains forever and forever, worlds without end, and a portion of the Priesthood will go and redeem and build up the Center Stake of Zion.
(Brigham Young, JD 11:12)
