32 Yea, 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.
The beautiful thing about this verse is that it focuses on being perfect in Christ rather than simply perfect in and of ourselves. Through the atonement, we can be justified and made pure through Christ’s grace. He is the source of our joy. He is the source of our consolation. It is only through him that we have a chance to come back to God. It is by his grace that we can become perfect. That is the message that ends the Book of Mormon. And it is a perfect capstone to a book that has been obsessively focused on Christ. Moroni at the end of his life and his work wants us to know that it is all about Christ. He does not want us to forget that central truth. Nothing else matters more to him than that.
