Therefore they were called after this holy order, and were sanctified, and their garments were washed white through the blood of the Lamb.  Now they, after being sanctified by the Holy Ghost, having their garments made white, being pure and spotless before God, could not look upon sin save it were with abhorrence; and there were many, exceedingly great many, who were made pure and entered into the rest of the Lord their God.

Alma 13:11-12
