1 John 4:9
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ἐν τούτῳ ἐφανερώθη ἡ ἀγάπη τοῦ Θεοῦ ἐν ἡμῖν, ὅτι τὸν υἱὸν αὐτοῦ τὸν μονογενῆ ἀπέσταλκεν ὁ Θεὸς εἰς τὸν κόσμον ἵνα ζήσωμεν δι᾽ αὐτοῦ.
This is how God’s love was revealed among us: God sent His one and only (note: Or only begotten or unique) Son into the world, so that we might live through Him.
