"If anyone makes the statement: “I love God,” and yet is hating his brother, he is a liar. For he who does not love his brother, whom he has seen, cannot be loving God, whom he has not seen" - 1 John 4:20
Here the Bible implies that it is far easier to love a visible person than an invisible one. Therefore if one lacks love for a visible person, how much more so he must lack love for the invisible God. Keeping this principle in mind note what Jesus says at Luke 14:26 and Matthew 10:37:
But according to the logical principle implicit at 1 John 4:20 wouldn't it be impossible for a modern day disciple to hate his visible relatives and yet love the invisible Christ? Wouldn't it be impossible for modern disciples to love the invisible Jesus more than their visible relatives? And so Jesus' words at Luke 14:26 and Matthew 10:37 implicitly refutes the logic underpinning 1 John 4:20. For the words of 1 John 4:20 implies that it is impossible for someone to love their visible fellow human less and claim to love the invisible God more."“If anyone comes to me and does not hate his father and mother and wife and children and brothers and sisters, yes, and even his own soul, he cannot be my disciple." - Luke 14:26
"He that has greater affection for father or mother than for me is not worthy of me; and he that has greater affection for son or daughter than for me is not worthy of me." - Matthew 10:37
And by the way, what kind of loving God would require his worshippers to have greater love for him than for their family - to sacrifice their family relationships for him? Why should a loving God put a father through the emotional agony of having to sacrifice his son to Him? What practical purpose does such devotion serve? Is God afraid that humans having more love for each other than for him would mean that they're likely to conspire together and overthrow him? Does he need something from us that he can only get if we love him more than our own relatives? These can't be because God is almighty and is not in need of anything from us. It's nothing but petty jealousy and ego. For a God that is almighty and not in need of anything, the God of the Bible is obscenely egocentric and selfish - much like the dictatorial kings who reigned in the ancient times the Bible was written in. I'm willing to bet that that's exactly who the Bible writers modeled the personality of Bible God after.
