“Bear fruits

Worthy of repentance!

Do not begin

To say to yourselves!

‘We have Abraham

As our ancestor!’

I tell you!

‘God is able

From these stones

To raise up children

To Abraham.

Even now,

The ax is lying

At the root of the trees.

Every tree

That does not bear

Good fruit

Is cut down

And thrown

Into the fire.’”

ποιήσατε οὖν καρποὺς ἀξίους τῆς μετανοίας· καὶ μὴ ἄρξησθε λέγειν ἐν ἑαυτοῖς Πατέρα ἔχομεν τὸν Ἀβραάμ· λέγω γὰρ ὑμῖν ὅτι δύναται ὁ Θεὸς ἐκ τῶν λίθων τούτων ἐγεῖραι τέκνα τῷ Ἀβραάμ.

ἤδη δὲ καὶ ἡ ἀξίνη πρὸς τὴν ῥίζαν τῶν δένδρων κεῖται· πᾶν οὖν δένδρον μὴ ποιοῦν καρπὸν καλὸν ἐκκόπτεται καὶ εἰς πῦρ βάλλεται.

Here is the first of the sayings from the so-called Q source.  Both Matthew, chapter 3:9-10, and Luke here have the exact same wording in their presentations of John’s preaching to the people.  Instead of just the Pharisees and Sadducees, Luke has John address this to all the people coming to be baptized.  This saying emphasized deeds, rather than relying on ancestry.  They were to produce fruit that was worthy of repentance (ποιήσατε οὖν καρποὺς ἀξίους τῆς μετανοίας).  They had to perform good deeds.  They should not presume that because they have had Abraham as their father, as the privileged chosen ones (καὶ μὴ ἄρξησθε λέγειν ἐν ἑαυτοῖς Πατέρα ἔχομεν τὸν Ἀβραάμ), that all would go well for them.  Then John pointedly said to them (λέγω γὰρ ὑμῖν) that God had the power (ὅτι δύναται ὁ Θεὸς) to change stones and rocks into the children of Abraham (ἐκ τῶν λίθων τούτων ἐγεῖραι τέκνα τῷ Ἀβραάμ), a Hebrew play on words that was translated into Greek.  The axe was already lying at the foot of the trees, ready to go to work (ἤδη δὲ καὶ ἡ ἀξίνη πρὸς τὴν ῥίζαν τῶν δένδρων κεῖται).  Every tree that was not bearing or producing good fruit would be cut down (πᾶν οὖν δένδρον μὴ ποιοῦν καρπὸν καλὸν ἐκκόπτεται).  Then they would be thrown into the fire (καὶ εἰς πῦρ βάλλεται).
