They blaspheme the terms
But if these things are so, it is high time for those persons to deal faithfully with their own souls who are so far from finding in themselves this joyful assurance, that they fulfill the terms and shall obtain the promises of that covenant, as to quarrel with the covenant itself, and blaspheme the terms of it, to complain, "They are too severe, and no man ever did, or shall, live up to them." What is this but to reproach God, as if he were a hard master, requiring of his servants more than he enables them to perform; as if he had mocked the helpless works of his hands, by binding them to impossibilities, by commanding them to overcome where neither their own strength nor his grace was sufficient for them?
