John 15:1-6 ASV

1 I am the true vine, and my Father is the husbandman.
2 Every branch in me that beareth not fruit, he taketh it away: and every [branch] that beareth fruit, he cleanseth it, that it may bear more fruit.
3 Already ye are clean because of the word which I have spoken unto you.
4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; so neither can ye, except ye abide in me.
5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same beareth much fruit: for apart from me ye can do nothing.
6 If a man abide not in me, he is cast forth as a branch, and is withered; and they gather them, and cast them into the fire, and they are burned.
