How quickly they forget. The children of Israel had just be miraculously rescued from slavery in Egypt. God spoke directly to them from the mountain and entered into a blood covenant. They were to be God's treasured possession among all nations, God's holy priesthood. They simply had to keep their end of the covenant.
They didn't last 40 days before they turned to the status quo and crafted a Golden Calf.
This sermon explores how we, too, are regularly tempted to turn away from the wild claims of God's love for the whole world and hunker down into our familiar safety zones.
