This is My commandment, that you love one another as I have loved you, John 15-16.

Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. “I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you. “As the Father loved Me, I also have loved you; abide in My love. 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, that My joy may remain in you, and that your joy may be full. This is My commandment, that you love one another as I have loved you. Greater love has no one than this, than to lay down one’s life for his friends. You are My friends if you do whatever I command you.
John 15:4-5,7,9-14 - hNKJV
