John 15:4-5
Remain in Me, and I will remain in you. Just as no branch can bear fruit by itself unless it remains in the vine, neither can you bear fruit unless you remain in Me. I am the vine and you are the branches. The one who remains in Me, and I in him, will bear much fruit. For apart from Me you can do nothing.
Matthew 7:18,20
A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. So then, by their fruit you will recognize them.
Psalm 1:3
He is like a tree planted by streams of water, yielding its fruit in season, whose leaf does not wither, and who prospers in all he does.
John 12:24
Truly, truly, I tell you, unless a kernel of wheat falls to the ground and dies, it remains only a seed. But if it dies, it bears much fruit.
