Bring forth fruits meet for repentance

But when he saw many of the Pharisees and Sadducees
come to his baptism, he said unto them,
O generation of vipers,
who hath warned you to flee from the wrath to come?
Bring forth therefore fruits meet for repentance:
And think not to say within yourselves,
We have Abraham to our father:
for I say unto you, that God is able of these stones
to raise up children unto Abraham.
And now also the axe is laid unto the root of the trees:
therefore every tree which bringeth not forth good fruit
is hewn down, and cast into the fire.

Matt 3:7-10.

Beware of false prophets, which come to you in sheep's clothing,
but inwardly they are ravening wolves.
Ye shall know them by their fruits.
Do men gather grapes of thorns, or figs of thistles?
Even so every good tree bringeth forth good fruit;
but a corrupt tree bringeth forth evil fruit.
A good tree cannot bring forth evil fruit,
neither can a corrupt tree bring forth good fruit.
Every tree that bringeth not forth good fruit
is hewn down, and cast into the fire.
Wherefore by their fruits ye shall know them.

Matt 7:15-20.

For a good tree bringeth not forth corrupt fruit;
neither doth a corrupt tree bring forth good fruit.
For every tree is known by his own fruit.
For of thorns men do not gather figs,
nor of a bramble bush gather they grapes.
A good man out of the good treasure of his heart
bringeth forth that which is good;
and an evil man out of the evil treasure of his heart
bringeth forth that which is evil:
for of the abundance of the heart his mouth speaketh.

Luke 6:43-45.

Now the works of the flesh are manifest, which are these;
Adultery, fornication, uncleanness, lasciviousness,
Idolatry, witchcraft, hatred, variance,
emulations, wrath, strife, seditions, heresies,
Envyings, murders, drunkenness, revellings, and such like:
of the which I tell you before, as I have also told you in time past,
that they which do such things shall not inherit the kingdom of God.
But the fruit of the Spirit is love, joy, peace,
longsuffering, gentleness, goodness, faith,
Meekness, temperance: against such there is no law.

Gal 5:19-23.

He spake also this parable;
A certain man had a fig tree planted in his vineyard;
and he came and sought fruit thereon, and found none.
Then said he unto the dresser of his vineyard,
Behold, these three years I come seeking fruit on this fig tree,
and find none:
cut it down; why cumbereth it the ground?
And he answering said unto him,
Lord, let it alone this year also, till I shall dig about it, and dung it:
And if it bear fruit, well:
and if not, then after that thou shalt cut it down.

Luke 13:6-9.

I am the true vine, and my Father is the husbandman.
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.
Now ye are clean through the word which I have spoken unto you.
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.
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.
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.
If ye abide in me, and my words abide in you,
ye shall ask what ye will, and it shall be done unto you.
Herein is my Father glorified, that ye bear much fruit;
so shall ye be my disciples.

John 15:1-8.
