What happened was this: People knew God perfectly well, but when they didn't treat him like God, refusing to worship him, they trivialized themselves into silliness and confusion so that there was neither sense nor direction left in their lives. They pretended to know it all, but were illiterate regarding life. They traded the glory of God who holds the whole world in his hands for cheap figurines you can buy at any roadside stand.
So God said, in effect, "If that's what you want, that's what you get." It wasn't long before they were living in a pigpen, smeared with filth, filthy inside and out. And all this because they traded the true God for a fake god, and worshiped the god they made instead of the God who made them—the God we bless, the God who blesses us. Oh, yes!
We have sin headlining the news... Within one week we have had a congressman from Florida resign in discrace and three school shootings. Two of these had intents of sexual assult associated with them.
Do we need any more proof that what Paul wrote in Romans 1 is accurate?
My heart mourns with the parents who's children have been harmed in these events. My spirit grieves with those who are angered by these events.
