OET interlinear 1 YHN (1 JHN) 4:15

uW Translation Notes:

Note 1 topic: figures-of-speech / hypo

ὃς ἐὰν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστιν ὁ Υἱὸς τοῦ Θεοῦ, ὁ Θεὸς ἐν αὐτῷ μένει, καὶ αὐτὸς ἐν τῷ Θεῷ

(Some words not found in SR-GNT: Ὅς ἄν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστίν ὁ Υἱός τοῦ Θεοῦ ὁ Θεός ἐν αὐτῷ μένει καί αὐτός ἐν τῷ Θεῷ)

This can be translated as a conditional statement if that would be helpful in your language. John is saying that what he describes in the second phrase will happen only if what he describes in the first phrase happens. Then it will certainly happen. Alternate translation: [If someone confesses that Jesus is the Son of God, then God will remain in him and he will remain in God]

Note 2 topic: figures-of-speech / explicit

ὃς ἐὰν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστιν ὁ Υἱὸς τοῦ Θεοῦ

(Some words not found in SR-GNT: Ὅς ἄν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστίν ὁ Υἱός τοῦ Θεοῦ ὁ Θεός ἐν αὐτῷ μένει καί αὐτός ἐν τῷ Θεῷ)

The meaning of this expression is similar to the expression “the one who confesses the Son” in 2:23. See how you translated it there. Alternate translation: [Everyone who truly believes and acknowledges publicly that Jesus is the Son of God]

Note 3 topic: guidelines-sonofgodprinciples

ὁ Υἱὸς τοῦ Θεοῦ

the ¬the (Some words not found in SR-GNT: Ὅς ἄν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστίν ὁ Υἱός τοῦ Θεοῦ ὁ Θεός ἐν αὐτῷ μένει καί αὐτός ἐν τῷ Θεῷ)

Son of God is an important title for Jesus that describes his relationship to God.

Note 4 topic: figures-of-speech / ellipsis

ὁ Θεὸς ἐν αὐτῷ μένει, καὶ αὐτὸς ἐν τῷ Θεῷ

the ¬the (Some words not found in SR-GNT: Ὅς ἄν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστίν ὁ Υἱός τοῦ Θεοῦ ὁ Θεός ἐν αὐτῷ μένει καί αὐτός ἐν τῷ Θεῷ)

In the expression and he in God, John is leaving out some of the words that a sentence would need in many languages in order to be complete. These words can be supplied from the previous phrase. Alternate translation: [God remains in him and he remains in God]

Note 5 topic: figures-of-speech / metaphor

ὁ Θεὸς ἐν αὐτῷ μένει, καὶ αὐτὸς ἐν τῷ Θεῷ

the ¬the (Some words not found in SR-GNT: Ὅς ἄν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστίν ὁ Υἱός τοῦ Θεοῦ ὁ Θεός ἐν αὐτῷ μένει καί αὐτός ἐν τῷ Θεῷ)

See the discussion of the term “remain” in Part 3 of the Introduction to 1 John. In this instance, it seems to mean the same thing as in 2:6. See how you translated it there. Alternate translation: [God continues to have a close relationship with him, and he continues to have a close relationship with God]
