Atoning Sacrifice of Christ - Barbara W. Winder

"Joy is knowing that through the atoning sacrifice of Christ we can receive a remission of our sins, even as King Benjamin taught. His people prayed in great humility, having asked for forgiveness of their sins. “The Spirit of the Lord came upon them, and they were filled with joy, having received a remission of their sins, and having peace of conscience, because of the exceeding faith which they had in Jesus Christ"."
