Dear friends, since God loved us that much, we surely ought to love each other.
1 John 4:11
...And everyone who loves the Father loves his children, too.
1 John 5:1b
We need God's help to love each other as He expects of us, but it helps to remember that God loves ALL of us and thought we were worth dying for.
Don't think God care for us all? Then see what the Bible says...
Don’t you see how wonderfully kind, tolerant, and patient God is with you? Does this mean nothing to you? Can’t you see that his kindness is intended to turn you from your sin?
The Lord is good to everyone.
He showers compassion on all his creation.
...For he gives his sunlight to both the evil and the good, and he sends rain on the just and the unjust alike. If you love only those who love you, what reward is there for that? Even corrupt tax collectors do that much.
I'd like to to put a twist to Matthew 5:46 (listed above): If God loved only those who loved Him, what kind of a God would He have been?
I think we owe it to Him to try and love each other. EVERY each other, not just the ones we like.
