This chapter is based on the First Letter of Peter.
During the busy years that followed the Day of Pentecost, the apostle Peter worked untiringly to reach the Jews who came to Jerusalem at the time of the annual festivals. The talents he possessed were invaluable to the early Christian church. He carried a double responsibility: He was an effective witness about the Messiah to unbelievers, and at the same time strengthened the believers’ faith in Christ. ULe 189.1
After Peter had been led to surrender self and rely entirely on divine power, he received his call as an undershepherd. Christ had said to Peter before his denial, “When you have returned to Me, strengthen your brethren” (Luke 22:32), and these words told of the work he was to do for those who would come to the faith. Peter’s experience of sin and repentance had prepared him for this work. Not until he learned his weakness could he know the believer’s need to depend on Christ. He had come to understand that we can walk safely only as we rely on the Savior, in complete distrust of self. ULe 189.2
At the last meeting by the sea, Jesus tested Peter by repeating the question three times, “Do you love Me?” (John 21:15-17), and then He restored him to his place among the Twelve. Jesus gave him his work: he was not only to seek those outside the fold, but to be a shepherd to the sheep. ULe 189.3
Christ mentioned only one condition of service—“Do you love Me?” Knowledge, a generous spirit, eloquence, zeal—all are essential, but without the love of Christ in the heart, the Christian minister is a failure. This love is a living principle revealed in the heart. If the character of the shepherd illustrates the truth he teaches, the Lord will set the seal of His approval on the work. ULe 189.4
