The word of the Lord that came to Micah of Moresheth during the reigns of Jotham, Ahaz and Hezekiah, kings of Judah —the vision he saw concerning Samaria and Jerusalem.
2 Hear, O peoples, all of you,
listen, O earth and all who are in it,
that the Sovereign Lord may witness against you,
the Lord from his holy temple.
We don't like to be critisized, and that makes large parts of the Bible problematic, since they point out our flaws and transgressions. People generally prefer pats on the back to constructive criticism.
That meshes nicely with a quote I read earlier today from C.S. Lewis-“I didn’t go to religion to make me happy. I always knew a bottle of Port would do that. If you want a religion to make you feel really comfortable, I certainly don’t recommend Christianity.” The commentators on that Facebook post were giving Joel Osteen both barrels, but we can create a lot of the same effect by railing against other people's sins; its easy to rag on materialism when you don't have much and easy to rag on homosexual stuff when only a few people, if any, have struggles with it in the pews (if they did, you ran them off long ago).
It's harder to talk about things that we don't do well. Hospitality is one our pastor addressed; we don't do a good job of looking after the little guy as individuals beyond throwing a token dead president in the Christmas benevolence offering plate. That hits closer to home that some of the more esoteric sins that few people get involved with.
