John 15:11

⁹ As the Father has loved Me, so have I loved you. Remain in My love.

¹⁰ If you keep My commandments, 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 may be in you and your joy may be complete.

¹² This is My commandment, that you love one another as I have loved you.

¹³ Greater love has no one than this, that he lay down his life for his friends.
