Even if we accept human testimony, the testimony of God is greater. For this is the testimony that God has given about His Son.
Textus Receptus (TR) - 1 John 5:9 >Εἰ τὴν μαρτυρίαν τῶν ἀνθρώπων λαμβάνομεν, ἡ μαρτυρία τοῦ Θεοῦ μείζων ἐστίν· ὅτι αὕτη ἐστὶν ἡ μαρτυρία τοῦ Θεοῦ, ἣν μεμαρτύρηκε περὶ τοῦ υἱοῦ αὐτοῦ.
