My study buddy and I are taking a break, as we participate in a larger group study. (Esther provided by Love God Greatly. If you've never done one of their studies, you should give one a try.)
In the meantime, I'm going back to Romans to pick up where I left off with my reading prior to our Corinthians study.
Romans 2
Here Paul is speaking to the Romans about God's righteous judgment.
"1 You, therefore have no excuse, you who pass judgment on someone else, for at whatever point you judge the other, you are condemning yourself, because you who pass judgment do the same things." I don't think Paul is saying that those who judge always commit the same exact sins, but the root of their sins are the same... selfishness, lust, greed. He goes on in verses 2-3 to speak of how God's judgment is based on truth, and how do we think that we would escape that judgment any more than the one we are judging.
