“When Thou Art Converted, Strengthen Thy Brethren”
Luke 22:31–32
31 And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat:
32 But I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren.
President Dallin H. Oaks said:
“. . . [T]he Savior confirmed the importance of being converted, even for those with a testimony of the truth. In the sublime instructions given at the Last Supper, He told Simon Peter, ‘I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren’ (Luke 22:32).
“In order to strengthen his brethren—to nourish and lead the flock of God—this man who had followed Jesus for three years, who had been given the authority of the holy apostleship, who had been a valiant teacher and testifier of the Christian gospel, and whose testimony had caused the Master to declare him blessed still had to be ‘converted.’
“Jesus’s challenge shows that the conversion He required for those who would enter the kingdom of heaven (see Matt. 18:3) was far more than just being converted to testify to the truthfulness of the gospel. To testify is to know and to declare. The gospel challenges us to be ‘converted,’ which requires us to do and to become. If any of us relies solely upon our knowledge and testimony of the gospel, we are in the same position as the blessed but still unfinished Apostles whom Jesus challenged to be ‘converted.’”
