1 John 3:2-3

²Ἀγαπητοί, νῦν τέκνα θεοῦ ἐσμεν, καὶ οὔπω ἐφανερώθη τί ἐσόμεθα. οἴδαμεν ὅτι ἐὰν φανερωθῇ ὅμοιοι αὐτῷ ἐσόμεθα, ὅτι ὀψόμεθα αὐτὸν καθώς ἐστιν. ³καὶ πᾶς ὁ ἔχων τὴν ἐλπίδα ταύτην ἐπ' αὐτῷ ἁγνίζει ἑαυτὸν καθὼς ἐκεῖνος ἁγνός ἐστιν

1 John 3:2-3

Beloved, now we are children of God, and it has not yet been revealed what we will be.  We know that when it [what we will be] is revealed, we will be like him, because we will see him as he is.  And everyone who has this hope in him purifies himself as that one [Jesus] is pure.

A short one today.  The Greek can be very interesting at times.  Please note the brackets in which the pronouns are referring to.

καθὼς ἐκεῖνος ἁγνός ἐστιν [as that one is pure].  The use of ἐκεῖνος [that] is not uncommon.  It ἐκεῖνος is presented here in it’s masculine form, so it infers [he].  Many translations render this verse [as he is pure].  In it’s basic form, ἐκεῖνος means [that one] if it is standing alone, but there is no doubt that ἐκεῖνος is referring to Jesus in this text.  The NET Bible actually puts Jesus in it’s translation.
