The Romans honored the goddess Fortuna. They took themselves to live in a deterministic world, with no real meaning in life, no real hope. Luck was the best they had. When we read the Bible (in this case, God's words to the Exiles in Jeremiah 29), we see a very different world. God is an active agent, seeking our good in the midst of the forces arrayed against us. This God invites us to respond to his action, not just be passive recipients of the forces of the world.
