1 John 5:10
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ὁ πιστεύων εἰς τὸν υἱὸν τοῦ θεοῦ ἔχει τὴν μαρτυρίαν ἐν αὐτῷ· 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.
