Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God? Dost thou believe on the Son of God? - This was the same with, Dost thou believe on the Messiah? for these two characters were inseparable; see John 1:34, John 1:49; John 10:36; Matthew 16:16; Mark 1:1.
