Prophets throughout the ages have emphasized the dual requirements of (1) avoiding and overcoming bad and (2) doing good and becoming better. Consider the penetrating questions posed by the Psalmist:
“Who shall ascend into the hill of the Lord? or who shall stand in his holy place?
“He that hath clean hands, and a pure heart; who hath not lifted up his soul unto vanity, nor sworn deceitfully” (Psalm 24:3–4).
it is possible for us to have clean hands but not have a pure heart. Please notice that both clean hands and a pure heart are required to ascend into the hill of the Lord and to stand in His holy place.
Let me suggest that hands are made clean through the process of putting off the natural man and by overcoming sin and the evil influences in our lives through the Savior’s Atonement. Hearts are purified as we receive His strengthening power to do good and become better. All of our worthy desires and good works, as necessary as they are, can never produce clean hands and a pure heart. It is the Atonement of Jesus Christ that provides both a cleansing and redeeming power that helps us to overcome sin and a sanctifying and strengthening power that helps us to become better than we ever could by relying only upon our own strength. The infinite Atonement is for both the sinner and for the saint in each of us.
