Among the many things John’s Gospel teaches is a concise formula to discern Good from Evil. John records Jesus as saying:
The thief comes only to steal and kill and destroy. I came that they may have life, and have it abundantly. (John 10:10 NRSV)
In Greek it reads: ὁ κλέπτης οὐκ ἔρχεται εἰ μὴ ἵνα κλέψῃ καὶ θύσῃ καὶ ἀπολέσῃ· ἐγὼ ἦλθον ἵνα ζωὴν ἔχωσιν καὶ περισσὸν ἔχωσιν.
And so I would paraphrase it: The thief only comes for theft, murder, and destruction. I have come that they may not only survive, but thrive.
In the first sentence, Jesus lays out what is evil, anti-life, anti-Christ, and anti-God. In the second sentence, Jesus lays out what is good, enhances life, embodies Christ, and glorifies God.
