Tom, why should we love them all? How would it make sense to love both someone who is kind to me and someone who is cruel to me?
Even Bible God, who supposedly "loves" everyone, hates people. My bold below:
"And I will destroy your high places, and cut down your images, and cast your carcases upon the carcases of your idols, and my soul shall abhor you." Leviticus 26:30
"For the wicked boasteth of his heart's desire, and blesseth the covetous, whom the LORD abhorreth." Psalm 10:3
"When God heard this, he was wroth, and greatly abhorred Israel" Psalm 78:59
So God gets to hate people. Yet what does the Bible teach about people hating people? There are some mixed messages here:
"Do not hate your brother in your heart. Rebuke your neighbor frankly so you will not share in his guilt." Leviticus 19:17
"If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters--yes, even his own life--he cannot be my disciple." Luke 14:26
"Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him." 1 John 3:15
"Do not I hate them, O LORD, that hate thee? and am not I grieved with those that rise up against thee? I hate them with perfect hatred: I count them mine enemies." Psalm 139:21-22
Which is it? Don't hate? Do hate? Obviously, God gets a free pass on hate. And you get to hate others that hate God. Guess that flushes the whole hypocritical "love thy neighbor" thing down the toilet.
