That the blood of Chist will bring forgiveness of their sins.
How can blood save sins? Yet Mormons think that Jesus’ blood will get them into heaven. Here are some quotes:
the blood of Christ atoneith for their sins. – Mosiah 3: 16 (Book of Mormon)
remember that there is no other way nor means whereby man can be saved, only through the atoning blood of Jesus Christ – Helaman 5: 9 (Book of Moron)
And again, if ye by the grace of God are perfect in Christ, and deny not his power, then are ye sanctifyith 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. – Moroni 10: 33 (Book of Mormon)
