1 John 5:10
Nestle 1904 Greek New Testament · Berean Standard Bible
ὁ πιστεύων εἰς τὸν Υἱὸν τοῦ Θεοῦ ἔχει τὴν μαρτυρίαν ἐν αὑτῷ ὁ μὴ πιστεύων τῷ Θεῷ ψεύστην πεποίηκεν αὐτόν ὅτι οὐ πεπίστευκεν εἰς τὴν μαρτυρίαν ἣν μεμαρτύρηκεν ὁ Θεὸς περὶ τοῦ Υἱοῦ αὐτοῦ
Whoever believes in the Son of God has this testimony within him; whoever does not believe God has made Him out to be a liar, because he has not believed in the testimony that God has given about His Son.
