Peter was giving the people of his generation a heads up as to what they could expect. They had become “untoward.” That can’t signal anything good. Listeners would have sensed the smoke on the horizon and taken notice that they were being warned. Perhaps this, in part, is why there was such a response for salvation among the listeners of Peter’s sermon.
I don’t believe we’ll ever see any great moving of God like in generations gone by. I don’t believe we can sing “God Bless America” and think God still looks down and smiles upon our country like He once did. Can we expect God to bless a country that has fallen into such a state of ungodliness? It would be like asking, and expecting, God to bless Sodom and Gomorrah. Not gonna happen.
