John 15 Progression:

-Abide in me [15:4]

-Abide in my love (by obeying my commands) [15:9-10]

-Love one another [15:12]

True love is seen in:

1. Laying down our lives for one another, as Jesus laid down his life for us. (John 15:12)

2. Befriending one another, as Jesus befriended us. (John 15:15-16)

3. Serving one another, as Jesus served us. (John 13:1-17)
