Jesus Brought Redemption from the Fall of Adam
And the Messiah cometh in the fulness of time, that he may redeem the children of men from the fall. And because that they are redeemed from the fall they have become free forever, knowing good from evil; to act for themselves and not to be acted upon, save it be by the punishment of the law at the great and last day, according to the commandments which God hath given.
--2 Nephi 2:26
Jesus Christ, the Messiah, came in the Meridian of time to be our Redeemer, our Savior, to redeem us all from the fall of Adam. Adam fell so that man may come to the earth and partake upon their spirits a physical body. As a result of Christ’s atonement, man is free to act for himself, to make his own choices. If we choose the right, we enjoy freedom and liberty. If we choose the wrong, we will be acted upon in the form of punishment or our conscience making us feel guilty. Jesus made it possible to be free from sin to the highest extent possible. Our duty is to obey His laws and commandments with exactness.
"Adam fell that men might be, and men are that they might have joy." (2 Nephi 2:25)
