The whole sermon was titled, "Winter is gone." And that was the one point of the message. It was a riff on Songs chapter 2 and was an encouragement for people going through a difficult time, a winter.
This is part of the larger biblical debate on hope and calamity. Some of the poetic and wisdom books suggest that faithfulness is rewarded with blessing. Some others remind us that faithfulness is no guarantee of blessing. Sermons like this one are encouraging for some people in their distress and based on the crowd reaction, some of those people were there. I'm not that kind of person so I'm happy to step aside and let the encouragement reach those who need it.
