The heart of God, his intent and instruction, is the essence of what the prophet Jeremiah told his people in exile, and it's the essence of what we see God do through Creation and the formation of His people! When we are fruitful and increase, when we work for the "good," for peace and prosperity of the people with whom we live--especially in exile--we wade into the confluence of the sacred and secular. The physical and spiritual. And this has always been God's purpose for his people.
