Could God really do far more than we could ever ask or deserve?

Oh yes! By his awesome power he is able to work within us. God is able to turn around every bad situation in our lives so that it will be to our benefit. God is able to bring changes to our lives, changes for our good, but we must trust him, we must believe that he is able and the God we serve will always keep his promise, we just need to be true to him always.
