It was the fact that they came from a long line of rebellion. The problems they had were a deep and abiding heritage. Even while they were in their kingdom, enjoying your great goodness to them in the spacious and fertile land you gave them, they did not serve you or turn from their evil ways. There is something instinctive in us that makes us fall into the same ditch over and over again, that makes us devalue what God calls valuable. Some of what flows from that is the senseless violence that has occurred in every generation.
Neighbors live side by side and get along for many years.
But once the violence breaks out, they ferociously hate each other. There's something about how we were raised that has a profound influence. This time, Lord, it will be different. I will resist temptation. I won't be the same as I've always been.
