Sometimes I wonder if God desolates and destroys so that His People can have a chance to restore and redeem, to show love and grace, to help and serve, to reach and preach.
Edom was destroyed because of its evil deeds, yes. And then, the Israelites were not supposed to show mercy, yes. But we have a new command: Love one another.
And so when other people lose their “life” (things that make up their life) and curse God and wonder why He’s done this, first we must help them. We can share with them what God has said, but, remember, we must be “speaking the truth in love” (eph 4:15)
So, God destroys but he rebuilds through us, His Body.
