It is indeed faulty for all of us. Today we see as through a glass darkly, then we shall see face to face. It is our fallenness that prohibits us from having the clearest vision of Christ today and we must recognize that fact about ourselves with humility. But fortunately, our vision is also not what saves us—another 'cute' phrase, I suppose. Instead it is Christ's work on the cross, plus nothing. It is always that 'plus nothing' that leads us all into trouble. Mormons and Christians of all stripes alike.
Yet with Paul, "I am confident of this very thing, that He who began a good work in you will perfect it until the day of Christ Jesus." Phillipians 1:6
And I pray there are many who call themselves Mormon today who are in that category.
