He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
Textus Receptus (TR) - 1 John 5:10 >Ὁ πιστεύων εἰς τὸν υἱὸν τοῦ Θεοῦ ἔχει τὴν μαρτυρίαν ἐν ἑαυτῷ· ὁ μὴ πιστεύων τῷ Θεῷ ψεύστην πεποίηκεν αὐτόν, ὅτι οὐ πεπίστευκεν εἰς τὴν μαρτυρίαν, ἣν μεμαρτύρηκεν ὁ Θεὸς περὶ τοῦ υἱοῦ αὐτοῦ.
