John 3:19

αὕτη δέ ἐστιν ἡ κρίσις ὅτι τὸ φῶς ἐλήλυθεν εἰς τὸν κόσμον καὶ ἠγάπησαν οἱ ἄνθρωποι μᾶλλον τὸ σκότος ἢ τὸ φῶς· ἦν γὰρ αὐτῶν πονηρὰ τὰ ἔργα.

And this is the judgment that the light had come into the world and the people loved the darkness rather than the light because their deeds were evil


 * One of the easier verses to read early on. Almost every word is in the first 300 to learn.
 * αὕτη - this, why feminine? It refers to ἡ κρίσις which is feminine. ἡ κρίσις ends with ς so it looks masculine but no! Fortunately one can always rely on the article.
 * ἐλήλυθεν - perfect active indicative 3P sg. The reduplication is clear. From ἔρχομαι. Must recognise ἔρχομαι and remember its step-brother root *ἦλθ (which is far more common)
 * ἠγάπησαν - loved. Nice regular aorist active indicative 3P pl. Views the evil acts of mankind as a whole rather than as an ongoing process--this is in the course of (final) judgment after all.
 * ἦν γὰρ αὐτῶν πονηρὰ τὰ ἔργα - I thought it was because of their evil deeds but the ἦν and the position of πονηρὰ before the τὸ it should have been obvious that we are seeing a predicate here. τὰ ἔργα is the subject. Always remember the article indicates the subject.
