One would not demand a contract or pledge from someone he was certain would fulfill his obligations even earlier than required and with more than expected. We have seen the Creator of the World perform this for us again and again with tremendous chesed and kindness. To ask GD for pledges and guarantees when he has shown us these characteristics is reprehensible.
