Matt 3:
8 Bring forth therefore fruits meet for repentance:
9 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.

Now, John is still addressing the Pharisees and the Sadducees.
John, is chastising them, and at the same time, instructing them.

"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."

John is telling them to prove themselves worthy or fit to be forgiven of their sins by doing goodly acts.
And, he continues to chastise and instruct them by demanding that they use not Abraham's name as their credentials.
Each individual is responsible for their own actions. And, just because one is a descendant of a good man, does not mean that the individual is also good.

How many today claim that they are goodly servants unto our FATHER, just because they were born a "Christian"?

Just because one may be a descendant, of let's say, Albert Einstein, doesn't necessarily mean the descendant is also a genius.

FATHER can give gifts (talents) to whomever HE chooses.
HE blesses those who deserve to be blessed, and according to HIS Will and Divine Purpose.

"for I say unto you, that God is able of these stones to raise up children unto Abraham."

"unto Abraham"
11 Abraam (ab-rah-am');

85 ademoneo-
to be troubled, great distress or anguish, depressed. This is the strongest of the three Greek words (See 0085, 0916, 3076) in the New Testament for depression.

There are two who can be called "father of a multitude".
There is the True Rock (foundation cornerstone), and there is the false or spurious rock.

"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 think not"
This is an idiom, which means: 'Don't even think for a moment that...' or 'Don't be of the opinion...'

So, let's read this again.
'Don't even think for a moment, that just because you are flesh descendants of Abraham, that this makes you a good servant unto YAHOVAH. I maintain and affirm that YAHOVAH has the power and ability to have each come through in the flesh according to that which each has earned, and according to which 'father' you have followed after.'


Matt 3:
10 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.

What is the "axe" or instrument which YAHOVAH sent into the earth in the flesh?
HE sent that part of HIMSELF, YAHSHUA, JESUS CHRIST.
YAHSHUA was already in the world in the flesh, although HIS 3 1/2 year ministry and calling forth of HIS government had not yet commenced...but it was about to begin.

The "axe" is already laying ready (at that moment) at the root of all the 'family trees', at the roots of each lineage, at the patriarchal beginnings of each seedline in the flesh.
And, each of these, who bring forth evil offspring and bad acts, shall be hewn down.

Isa 10:33-34
33 Behold, the Lord, the LORD of hosts, shall lop the bough with terror: and the high ones of stature shall be hewn down, and the haughty shall be humbled.
34 And he shall cut down the thickets of the forest with iron, and Lebanon shall fall by a mighty one. (KJV)

YAHSHUA is still the "axe", which when HE returns, shall cleave and separate those who have overcome from those who have not. And, this shall be according to each individual's fruits (acts) that they have brought forth.
