Lehi once again weaves in the mission of the Messiah. The redemption of mankind is equally essential to the ability to act upon choices. The conditions that can exalt us are created by two important sets of circumstances, the allowance of opposition (brought about through the Fall) and our potential redemption (brought about by Christ's atonement). These two conditions together provide the groundwork. With them we are "free forever." With our knowledge of good and evil (the instigation of opposites) we are able to act for ourselves to choose. It is this choosing of the good that exalts us. To make sure that we understand the good, God has given us commandments, so that by choosing to obey them, we might find joy.
