Therefore you have no excuse, whoever you are, when you judge others; for in passing judgment on another you condemn yourself, because you, the judge, are doing the very same things. You say, “We know that God’s judgment on those who do such things is in accordance with truth.” Do you imagine, whoever you are, that when you judge those who do such things and yet do them yourself, you will escape the judgment of God? Or do you despise the riches of his kindness and forbearance and patience? Do you not realize that God’s kindness is meant to lead you to repentance? But by your hard and impenitent heart you are storing up wrath for yourself on the day of wrath, when God’s righteous judgment will be revealed. For he will repay according to each one’s deeds: to those who by patiently doing good seek for glory and honor and immortality, he will give eternal life; while for those who are self-seeking and who obey not the truth but wickedness, there will be wrath and fury.
Fundamentalists always read stuff like this and think it’s talking about “those people” outside of the Church. But this passage is talking to Jewish Christians! It’s talking to the very people who would presume their security and election (*cough* like many fundamentalists *cough*) . But you know what? Paul never says they’re wrong in their security and election! And yet he still says there will be wrath and fury. Might those things not be mutually-exclusive? An important theme here is that God’s people bear the brunt of God’s judgment, not the rest of the world. These verses are speaking to Christians, not “those people”. God’s people will face the possibility of God’s fire (but might it be refining fire?). This is very much what Lesslie Newbigin wrote about when he talked about election.
