1 João 3

16 We know what love is–through Christ's having laid down His life on our behalf; and in the same way we ought to lay down our lives for our brother men.

17 But if any one has this world's wealth and sees that his brother man is in need, and yet hardens his heart against him–how can such a one continue to love God?

18 Dear children, let us not love in words only nor with the lips, but in deed and in truth.
