Discovery BoxLuke 3:8-9 
Context3:8 Therefore produce 1 fruit 2 that proves your repentance, and don’t begin to say 3 to yourselves, ‘We have Abraham as our father.’ 4 For I tell you that God can raise up children for Abraham from these stones! 5 3:9 Even now the ax is laid at the root of the trees, 6 and every tree that does not produce good fruit will be 7 cut down and thrown into the fire.”
1 tn The verb here is ποιέω (poiew; see v. 4).
2 tn Grk “fruits.” The plural Greek term καρπούς has been translated with the collective singular “fruit” (so NIV; cf. Matt 3:8 where the singular καρπός is found). Some other translations render the plural καρπούς as “fruits” (e.g., NRSV, NASB, NAB, NKJV).
3 tn In other words, “do not even begin to think this.”
4 sn We have Abraham as our father. John’s warning to the crowds really assumes two things: (1) A number of John’s listeners apparently believed that simply by their physical descent from Abraham, they were certain heirs of the promises made to the patriarch, and (2) God would never judge his covenant people lest he inadvertently place the fulfillment of his promises in jeopardy. In light of this, John tells these people two things: (1) they need to repent and produce fruit in keeping with repentance, for only that saves from the coming wrath, and (2) God will raise up “children for Abraham from these stones” if he wants to. Their disobedience will not threaten the realization of God’s sovereign purposes.
5 sn The point of the statement God is able from these stones to raise up children to Abraham is that ancestry or association with a tradition tied to the great founder of the Jewish nation is not an automatic source of salvation.
6 sn Even now the ax is laid at the root of the trees. The imagery of an “ax already laid at the root of the trees” is vivid, connoting sudden and catastrophic judgment for the unrepentant and unfruitful. The image of “fire” serves to further heighten the intensity of the judgment referred to. It is John’s way of summoning all people to return to God with all their heart and avoid his unquenchable wrath soon to be poured out. John’s language and imagery is probably ultimately drawn from the OT where Israel is referred to as a fruitless vine (Hos 10:1-2; Jer 2:21-22) and the image of an “ax” is used to indicate God’s judgment (Ps 74:5-6; Jer 46:22).
7 tn Grk “is”; the present tense (ἐκκόπτεται, ekkoptetai) has futuristic force here.
