Moroni 10

In his final writings, Moroni wrote -

"...I would exhort you that ye deny not the power of God; for he worketh by power, according to the faith of the children of men..." (Book of Mormon Moroni 10:7)

The scriptures speak of the power of the Holy Ghost, the power of faith, the power of the priesthood, the power of the atonement, the power of the resurrection - all being the power of God. Basically, the powers that God possesses which is -

"...the power of God unto salvation..." (New Testament Romans 1:16)

Where power is grace, which -

"...grace is an enabling power that allows men and women to lay hold on eternal life and exaltation after they have expended their own best efforts." (Bible Dictionary G Grace:Entry)

Therefore -

"...come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; and if ye shall deny yourselves of all ungodliness, and love God with all your might, mind and strength, then is his grace sufficient for you, that by his grace ye may be perfect in Christ; and if by the grace of God ye are perfect in Christ, ye can in nowise deny the power of God.
33 And again, if ye by the grace of God are perfect in Christ, and deny not his power, then are ye sanctified in Christ by the grace of God, through the shedding of the blood of Christ, which is in the covenant of the Father unto the remission of your sins, that ye become holy, without spot." (Book of Mormon Moroni 10:32 - 33)

Enabling man to lay hold of eternal life and exaltation.
