Interesting in view of Luke 9:49-50:
49 John answered, “Master, we saw someone casting out demons in your name, and we tried to stop him, because he does not follow with us.” 50 But Jesus said to him, “Do not stop him, for the one who is not against you is for you.”
Perhaps it's the natural inclination for all of us to look at others and simply condemn them whoever they are because they "do not follow with us". May the Lord have mercy on us all.
