"And then shall the power of heaven come down among them; and I also will be in the midst."
What does the "power of heaven" include? (We've already looked at 1 Nephi 14: 14 which is speaking about this same event, you should read again that post.)
What is the difference between the "power of heaven" and the Lord's presence?
Why would the power of heaven come first, then the Lord? (Moses 1: 11.)
What would it require for you to be able to endure the presence of the Lord? (Moses 1: 2.)
If you are not prepared for His presence, what will your reaction be? (Mormon 9: 3-5.)
Those who are directly in a covenant with Him, who have been promised forgiveness of their sins by Him, and who have sought and obtained His face, will be able to dwell in His presence. They will be prepared for His glory, have part in it, and thereby be protected when they are with Him.
If people have the "power of heaven" with them, do they need some other means to protect them as well? Why not?
Haven't we already been promised this as early as 1833? (See D&C 97: 15-19.) What happened that we did not obtain these things? Have our Temples been kept undefiled? If not, why? Have we permitted the unclean to enter? If so, why? Is the glory of the Lord in our Temples? Can we behold His presence there? If not, why not?
If the promise was made to us in 1833 and we haven't realized it from then till now, then are we to be numbered among those who will have the Lord "in their midst" as set out in this verse? What should we do to change that?
By and large, the church has failed to honor the Book of Mormon, keep its terms and become heirs of its promises. Our collective failure does not prevent individual success. Individuals may still realize the blessings offered. But each of us must meet the exact same conditions. Having met them, however, nothing can prevent you from obtaining the blessings.
The Lord has been willing to bring individuals back into His presence on the same conditions throughout all time. Read again The Second Comforter if you do not remember what those conditions are. He is as willing to make you a citizen of Zion, member of the church of the Firstborn, and part of the general assembly today (D&C 76: 66-69) as in the future established Zion spoken of in the verses we have been reviewing. Many have done it in times past. Some have done it in our day. All are offered the same opportunity, but always on the same conditions.
The unchanging Gospel of Jesus Christ is always the same, and its blessings are always available.
