The safety of appearing at the day of judgement, in the righteousness of Christ

There is a necessity of our having the righteousness of the Law: God has stated the Law to be a rule of his proceeding towards man: wherein he has set down the terms upon which he will bestow life and execute death; in that Covenant, he gave not only a Law unto man, but likewise to himself, from which he will never swerve. O it is utterly vain for any man to expect acceptance with God without that righteousness which the Law requires; until the Law be answered, man can lay no claim to blessedness: neither can God in faithfulness bestow blessedness upon man: God has bound himself to see the Law fulfilled to a tittle: this Law can't be abrogated nor disannulled: Saints indeed are not under the condemning power of it; because it has been fulfilled for them: but yet the Law stands in force; as a rule according to which God will distribute eternal rewards, Math ⟨p. 25⟩5.18. One jot, or one tittle of the Law shall in no wise pass, till all be fulfilled: man may break the Law, but God will fulfil it; the Law is never out of date, and as it cannot be abrogated, so neither can it be moderated: God will never take up with less satisfaction then the Law admits of, nor with a less perfect Obedience then the Law requires: God does under the Gospel, accept of imperfect Obedience; but not for Justification. There can be no varying from the utmost and highest demands of the Law: the Law is unflexible, and must be exactly attended: it abates nothing: so that a regular conscience can never give peace until the Law be fully answered: the Law gives sin a condemning power, 1 Cor 15.56. the sting of death is sin, and the strength of sin is the Law: therefore the Law must be answered.
