John 15:10-13

If you keep My commandments, you will abide in My love; just as I have kept My Father’s commandments and abide in His love. These things I have spoken to you so that My joy may be in you, and that your joy may be made full. “This is My commandment, that you love one another, just as I have loved you. Greater love has no one than this, that one lay down his life for his friends.
