and many people came to him. They said, “Though John never performed a miraculous sign, all that John said about this man was true.”
There was a difference between Jesus and John. Here we see John praised but at the same time, his subordination to Jesus is stressed. John came proclaiming, but Jesus brought power. “John could diagnose the situation; Jesus brought the power to deal with the situation.” (Barclay)
“They had held John to be a prophet, yet when he searched for his credentials as a prophet, they found them inextricably intertwined with the claims of Jesus. John had failed to prove himself a prophet by miracles and signs—the accustomed credentials. But he had done so by his predictions which had come true, and all of these predictions related to Jesus.” McGarvey
When we know Christ by faith in our hearts, we find, like these people, all that the Scripture says of him is true.
