After all, he heard God’s calling to proclaim repentance in anticipation of the Messiah, directed his followers to Jesus, and only recognized Jesus as the Messiah when the sign was bestowed upon Him—the Spirit descending and resting on Him. John also acknowledged the voice of the Father regarding Jesus and later expressed joy at witnessing Jesus’ growing glory, indicating that he did not inquire solely for his disciples' sake. If John had his own uncertainties, he should not have turned to Jesus for reassurance. To do so would imply that John was questioning his role as the Forerunner, which would suggest he recognized Jesus as the Messiah without confirmation from Jesus. The phrasing "or else" implies that John's disciples held no doubts about John's identity but only about Jesus'. They believed John could maintain his status as Forerunner, even if Jesus were not the Messiah, suggesting that the Messiah's coming remained a possibility. Such sentiments, however, do not align with John's own convictions. If he had doubted Jesus, he would similarly question his own calling and reject the title of Forerunner altogether. John had received divine affirmation for both his mission and Jesus' identity.
Alternatively, one could interpret John's inquiry as not stemming from disbelief but from an eagerness to witness the establishment of the Messiah's kingdom and to be liberated from his imprisonment. However, it seems unlikely that John harbored such sentiments. He designated the Messiah as the Lamb and accepted that he would face opposition. It is improbable that he would align himself with a viewpoint anticipating a public establishment of the Messiah's reign that would alter the fate of the Forerunner. Thus, this questioning was unlikely to originate from John personally. Nevertheless, John, while in prison, summoned these disciples to send them to Jesus with this question, seeking clarity about any misconceptions regarding Jesus. It is highly plausible that the doubts raised in John's followers were instigated by the Pharisees, who attempted to sway sentiments against Jesus in Judea, and who, in Galilee, used John's disciples to criticize Jesus' followers for not fasting, a matter the Lord addressed in His teaching (see Mt 11:16-19).
