And now, my friends, good-bye! Strive for perfection; listen to my appeals; agree with one another; live in peace. And the God of love and peace will be with you.
Here is the clear difference between God's children and the Devil's children: those who do not do what is right or do not love others are not God's children.
And we ourselves know and believe the love which God has for us. God is love, and those who live in love live in union with God and God lives in union with them.
