He paid a debt He did not owe to free us from a debt we can never pay

"How can we ever repay the debt we owe to the Savior? He paid a debt He did not owe to free us from a debt we can never pay."

- Elder Joseph B. Wirthlin, Of the Quorum of the Twelve Apostles, "Earthly Debts, Heavenly Debts," Ensign, May 2004, p. 43
