2 Now when John had heard in the prison the works of Christ, he sent two of his disciples, 3 And said unto him, Art thou he that should come, or do we look for another? (Matthew 11:2-3 KJV)
William Burkitt’s Commentary
It was not for John’s information that he sent his disciples to Jesus, but for their satisfaction; that he was the true and promised Messiah; John was assured of it himself by a sign from heaven at our Saviour’s baptism, Mt 3:17. But John’s disciples out of great zeal to him their master, envied Christ himself, and were unwilling to believe any person greater than their master, (Archbishop Tillotson, vol.5) therefore John, out of a pious design to confirm his disciples in the belief of Jesus being the true Messias, sends them to our Saviour, to hear the doctrine which he taught, and to see the miracles which he wrought.
Learn hence, What a pious desire there is in such as know Christ experimentally themselves, to bring all that belong to them to a saving acquaintance with him. Archbp. Tillotson, Vol. V.
