Joseph Smith Quotes

The doctrine or sealing power of Elijah is as follows: If you have power to seal on earth and in heaven, then we should be wise. The first thing you do, go and seal on earth your sons and daughters unto yourself, and yourself unto your fathers in eternal glory.
This is the spirit of Elijah, that we redeem our dead, and connect ourselves with our fathers which are in heaven, and seal up our dead to come forth in the first resurrection; and here we want the power of Elijah to seal those who dwell on earth to those who dwell in heaven.
