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.
Mat 7: 18 - 20
A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. 19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. 20 Therefore by their fruits ye shall know them.
Psa 1: 3
And he shall be like a tree planted by the streams of water, that bringeth forth its fruit in its season, whose leaf also doth not wither; whatsoever he doeth shall prosper.
John 12: 24
Verily, verily, I say unto you, Except a grain of wheat fall into the earth and die, it abideth by itself alone; but if it die, it beareth much fruit.
