If God did not bless, not one hair, not a solitary wisp of straw, would grow; but there would be an end of everything. At the same time God wants me to take this stance: I would have nothing whatever if I did not plow and sow. God does not want to have success come without work, and yet I am not to achieve it by my work. He does not want me to sit at home, to loaf, to commit matters to God, and to wait till a fried chicken flies into my mouth. That would be tempting God.

Martin Luther, quoted in What Luther Says
