The Savior concludes his teaching to the Nephite masses by administering the sacrament through His apostles and teaching about the gathering of Israel. He makes sure their scriptures include important events and teachings that they had failed to record, including evidence of His ability to overcome death on behalf of everyone, which is the fundamental purpose of the atonement. He teaches the importance of tithing, but not as a way for us to achieve temporal security, but for spiritual blessings, including those relating to our families. Mormon did not record all of Christ’s teachings, but if we are to know what else Christ taught we must seek for it ourselves.
