1 John 3:16, 17, 23

This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters.

If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person?

And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us.
