"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."
Mat 7: 18 - 20
"A sound tree cannot bear evil fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus you will know them by their fruits.".
Psa 1: 3
He is like a tree planted by streams of water, that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers.
John 12: 24
"Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit."
