“You are to testify!
You also are my witnesses!
Because you have been
From the beginning.”
καὶ ὑμεῖς δὲ μαρτυρεῖτε, ὅτι ἀπ’ ἀρχῆς μετ’ ἐμοῦ ἐστε.
John uniquely indicated that Jesus said that now they were to testify or be his witnesses (καὶ ὑμεῖς δὲ μαρτυρεῖτε), because these disciples had been with him (μετ’ ἐμοῦ ἐστε) from the beginning (ὅτι ἀπ’ ἀρχῆς). Now the disciples and the apostles of Jesus, his followers, would take on a new role. They would have to testify and bear witness in public about Jesus, because they had been with him in his public ministry since its inception. Are you willing to testify about Jesus?
