ὁ λέγων ἐν τῷ φωτὶ εἶναι καὶ τὸν ἀδελφὸν αὐτοῦ μισῶν ἐν τῇ σκοτίᾳ ἐστὶν ἕως ἄρτι   ὁ ἀγαπῶν τὸν ἀδελφὸν αὐτοῦ ἐν τῷ φωτὶ μένει καὶ σκάνδαλον ἐν αὐτῷ οὐκ ἔστιν  ὁ δὲ μισῶν τὸν ἀδελφὸν αὐτοῦ ἐν τῇ σκοτίᾳ ἐστὶν καὶ ἐν τῇ σκοτίᾳ περιπατεῖ καὶ οὐκ οἶδεν ποῦ ὑπάγει ὅτι ἡ σκοτία ἐτύφλωσεν τοὺς ὀφθαλμοὺς αὐτοῦ

You might think you’re taking in the sunshine, but if you’ve got hate for someone in your life, it’s not a sunrise you’re seeing. It’s a sunset.  Darkness is closing in on you.  But if you’ve got love for the people in your life, you’ve got nothing to worry about.  Take in the warmth of the sun.  But don’t forget, once you hate, your surroundings change from day to night.  Hate is like wandering lost in the darkness - without direction. 
Hate blinds.
