The gospel does not lower the standard of perfection. It commands all that the law commands, in the same holiness and purity. "Be perfect as your heavenly Father is perfect," and "Be holy, for I am holy," remain gospel commands. The difference is in acceptance, not in requirement. The gospel pardons our failures, but it does not dispense with any of God's commands.https://www.monergism.com/modest-survey-secrets-antinomianism-ebook
Take heed that you rest not satisfied with that knowledge of Christ you have attained, but grow on towards perfection. It is the pride and ignorance of many professors, when they have got a few raw and undigested notions, to swell with self-conceit of their excellent attainments. And it is the sin, even of the best of saints, when they see (veritas in profundo) how deep the knowledge of Christ lies, and what pains they must take to dig for it, to throw by the shovel of duty, and cry, Dig we cannot. To your work, Christians, to your work; let not your candle go out: sequester yourselves to this study, look what intercourses, and correspondence are betwixt the two world; what communion soever God and souls maintain, it is in this way; count all, therefore, but dross in comparison of that excellency which is in the knowledge of Jesus Christ.
