President Boyd K. Packer taught "There is no habit, no addiction, no rebellion, no transgression, no apostasy, no crime exempted for the promise of complete forgiveness. That is promise of the atonement of Christ."
We are all precious,each one of us. Every soul can again be pure as we have faith in Christ, repent for our sins, going to him in prayer with a broken heart and contrite spirit truly wanting to be better. We come to feel him in our hearts, feeling his love for us and once that connection happens our lives change. This knowledge of the atonement brings comfort and peace as we use it in our daily lives, the atonement is infinite and eternal, yet it is applied to us individually, one person at a time. I know that the atonement is real and that Christ will always be there lifting us up. He lived a perfect life here on the earth, he atoned for our sins and he does live, now and forever.
