The angel speaking to King Benjamin undoubtedly understood doctrine better than we do. If we proceed with that premise then we can learn some things we don’t presently know. We can correct the errors we presently have. It is preferable that we allow scriptures to inform us than for us to distort the scriptures to fit our preconceived notions.
The angel declares:
Christ is “the Lord Omnipotent.”
Christ is the one “who reigneth” in heaven.
Christ is “from all eternity to eternity.”
Christ is the one who will “come down from heaven among the children of men.”
Though He is a glorified, eternal God, reigning in heaven, and holding the power to exist from eternity to eternity, He will condescend to “dwell in a tabernacle of clay.” (Mosiah 3: 5.)
If you can take that in, then you can understand what Joseph Smith said about “sons of God, who exalt themselves to be gods, before they were born.” (TPJS, p. 375.)
To be “exalted” is to already be in possession of what we hope to acquire in mortality. That is, Christ was already exalted. He did not come here for His advancement, according to this angel, but He came and descended into a “tabernacle of clay” in order to serve us.
They (the noble and great) prove us. They (the noble and great) are not being proven. They are already proven, and have exalted themselves to be gods. This doctrine being taught by the angel to Benjamin agrees with Joseph Smith’s Nauvoo era sermons and the lessons in the Book of Abraham. At the end, Joseph was beginning to appreciate the doctrine of the Book of Abraham.
The “Lord Omnipotent” was to put His great power on display by “working mighty miracles” among men. These were to include “healing the sick, raising the dead, causing the lame to walk, the blind to receive their sight, and the deaf to hear, and curing all manner of diseases.” (Mosiah 3: 5.) In other words, the Omnipotence of the Lord would not be diminished by the tabernacle of clay He would inhabit. He would bring power with Him, rather than needing power to be given to Him.
It is true enough that He would come with a veil of forgetfulness. He would have to endure the frailties of the tabernacle of clay. He would need to study, search, pray and submit. He would have to walk the exact same path which all of us are required to walk.
It is the great condescension of God because God left His place of glory, descended here and reversed the grip of death on mankind. Once we read the words of the angel, none of us can be mistaken about how great the God’s descent was to accomplish this rescue mission. This is not merely “our older Brother” who came here. He is much more, and we are ever indebted to Him.
His power includes and has always included the commanding of devils and casting out evil spirits which men allow to dwell in their hearts. (Mosiah 3: 6.) He subdued them before and they are required to obey Him here. Though He allowed Michael to physically cast them from heaven (Rev. 12: 7-9), it was Christ who accomplished the victory there (Moses 4: 3), and limited Lucifer’s power here.
Notice the location of the evil spirits that Christ will cast out. It is from “the hearts of the children of men.” (Mosiah 3: 6.) It is in our heart that we dwell on lusts, ambition, unholy desires, anger, jealousy and resentments. It is the center of our feelings that we permit evil to dwell. Christ’s victory goes directly to our hearts.
