Love and hate can't cohabitate.

"Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen." 1 John 4:20 

Why not? I have people in my life who get me and I'm on their wavelength. I have warm feelings for them and they for me. Others don't understand me nor I them. Neither of us desire to change that relationship. In fact, we harbor the chill of misunderstanding and hate between us. What does this lack of relationship have to do with the fire of our passion for God?
Hate keeps me focusing on me. Every perceived spiteful act of that other person drills me deeper into myself. Soon many of my relationships become tainted by selfishness. When folks don't respond as I desire, a frostbite of selfishness cuts in between. The frost of hate leads the way through my life for the dead cold of bitterness. Slicing emotional winds of hate tear apart God's passion in me, reducing our love to coals and smoking ruins.
