How do we know that Jesus defended John the Baptist?

In Luke 7:24-30, after John's messengers departed, Jesus began to speak highly of John the Baptist, emphasizing his role as 'more than a prophet.' Christ's remarks serve to elevate John's stature among the crowd, countering any doubts they might have had due to John's imprisonment. This public commendation not only affirms John's prophetic mission but also serves as an assurance to believers facing accusations or slander. Jesus, as our Advocate, promises to uphold the dignity of those who faithfully serve Him, assuring that their worth is affirmed in the eyes of God regardless of their earthly circumstances.
