I am the vine; you are the branches.  Whoever abides in me and I in him, he it is that bears much fruit, for apart from me you can do nothing. 

If anyone does not abide in me he is thrown away like a branch and withers;and the branches are gathered, thrown into the fire, and burned. If you abide in me, and my words abide in you, ask whatever you wish, and it will be done for you. By this my Father is glorified, that you bear much fruit and so prove to be my disciples.  As the Father has loved me, so have I loved you. Abide in my love.

John 15:5-9
