Rather than providing a straightforward response to John's inquiry, Jesus seemed to evoke Isaiah’s prophecy when He instructed them, “Go and report to John what you have seen and heard: the blind regain their sight, the lame walk, those afflicted with leprosy are cleansed, the deaf hear, the dead are raised, and the poor have the gospel preached to them.” While Jesus’ reply was indirect, it should have been clear to John's disciples that they were to relate to John everything they witnessed and heard, echoing the words of Isaiah: “Be strong and courageous; do not fear; here is your God, and He will save you!” They should have grasped this message, especially since Jesus concluded with, “Blessed is anyone who does not stumble on account of me,” implying that those who do not doubt His identity as the awaited Messiah are truly blessed.
However, it is uncertain whether John’s disciples interpreted Jesus’ words correctly. The Evangelists do not reveal their understanding. The multitude of healings and miraculous occurrences should have profoundly affected their hearts, which had not yet turned toward Jesus. Those who were healed of their ailments, those who received sight or regained the ability to speak, all those who struggled and the spiritually impoverished proclaimed the glory of Jesus. John's disciples had only to embrace this joyful message, and many likely did come to see Jesus as the true Messiah; yet, not all did. Some persisted in their disbelief, eventually forming a distinct sect after John's death.
Upon their departure, the disciples might have unintentionally sparked doubt among those around Jesus. Many could have speculated that John himself was questioning Jesus, asking, “Is He the One who is to come, or should we await another?” Such a question would cast doubt on John, suggesting that he had once misidentified Jesus at the Jordan and, being cautious in his imprisonment, now questioned His true identity as the Lamb who takes away the sins of the world. To counter these potential misgivings, it was vital to remind people of John’s influential role, how crowds flocked to him in the wilderness to hear his message of repentance and the coming kingdom, how he boldly scolded the Pharisees and Sadducees, and the responses he gave to those sent by the chief priests.
