John 15:2-6
King James Version (KJV)
2 Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit.

3 Now ye are clean through 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; no more 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 bringeth forth much fruit: for without me ye can do nothing.

6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.


Romans 11:15-24
King James Version (KJV)
15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?

16 For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.

17 And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree;

18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.

19 Thou wilt say then, The branches were broken off, that I might be grafted in.

20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:

21 For if God spared not the natural branches, take heed lest he also spare not thee.

22 Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.

23 And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graft them in again.

24 For if thou wert cut out of the olive tree which is wild by nature, and wert grafted contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be grafted into their own olive tree?
