John 15:10-13

If you keep My commandments and obey My teaching, you will remain in My love, just as I have kept My Father’s commandments and remain in His love. I have told you these things so that My joy and delight may be in you, and that your joy may be made full and complete and overflowing. “This is My commandment, that you love and unselfishly seek the best for one another, just as I have loved you. No one has greater love [nor stronger commitment] than to lay down his own life for his friends.
