To what he has seen
Yet no one receives
John uniquely had John the Baptist present the same comment that Jesus had given to Nicodemus in verse 11, about the non-acceptance of the message. John the Baptist said that Jesus, using the third person singular pronoun, testified (τοῦτο μαρτυρεῖ) to what he has seen (ὃ ἑώρακεν) and heard (καὶ ἤκουσεν αὐτοῦ), but no one accepted or received (οὐδεὶς λαμβάνει) his testimony (καὶ τὴν μαρτυρίαν). This seemed like Jesus had no disciples, that everybody had rejected Jesus, the one from above. No one had accepted his message. Are you willing to accept the testimony of Jesus?
