Perversion of God's Law

Neonomians allege, that though we cannot fulfil that perfect obedience which the law of works demanded, yet God has been graciously pleased, for Christ’s sake, to give us a new law, according to which, sincere obedience, or faith, repentance, and sincere obedience, are accepted as our justifying righteousness. It may be here remarked, that the Scripture nowhere gives the slightest intimation that a near and milder law has been substituted in place of the law of works originally given to man. Christ came "not to destroy the law, but to fulfil it." The gospel was never designed to teach sinners that God will now accept of a sincere instead of a perfect obedience, but to direct them to Jesus Christ as "the end of the law for righteousness to every one that believeth." The idea of a new law, adapted to the present condition of human nature, reflects the greatest dishonour both upon the law and the Lawgiver; for it assumes that the Lawgiver is mutable, and that the law first given to man demanded too much. - IX. Of Justification
