John 15: 4 - 10
4 Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me.
5 I am the vine, you are the branches. He who abides in me, and I in him, he it is that bears much fruit, for apart from me you can do nothing.
6 If a man does not abide in me, he is cast forth as a branch and withers; and the branches are gathered, thrown into the fire and burned.
7 If you abide in me, and my words abide in you, ask whatever you will, and it shall be done for you.
8 By this my Father is glorified, that you bear much fruit, and so prove to be my disciples.
9 As the Father has loved me, so have I loved you; abide in my love.
10 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.
