"A new command I give you: Love one another. As I have loved you, so you must love one another.
If it is possible, as far as it depends on you, live at peace with everyone.
1 John 4:19-21
We love because he first loved us. If anyone says, "I love God," yet hates his brother, he is a liar. For anyone who does not love his brother, whom he has seen, cannot love God, whom he has not seen. And he has given us this command: Whoever loves God must also love his brother.
Make every effort to live in peace with all men and to be holy; without holiness no one will see the Lord.
