The world, at least our world, is changeable. Besides, we are not alone. All the people are God's creatures. He equally loves them, and asks us to love each other as well. People are not longer indifferently face to the others.
Fate plays a smaller role.

Atheists or Christians, we all are the result of this doctrine as part of our culture and civilisation, both concerning our good deeds and our evil ones as well. Christianity has made us active and enterprising people, sometimes too enterprising.
