Through Faith

 We are not said to be justified 𝘱𝘳𝘰𝘱𝘵𝘦𝘳 𝘧𝘪𝘥𝘦𝘮 (on account of faith) but 𝘱𝘦𝘳 𝘧𝘪𝘥𝘦𝘮 (through faith).

—Puritan Thomas Manton, Works 13:478

Faith is said to justify, because without it we cannot apprehend the righteousness of Christ; as the hand may be said to feed and nourish the body, but the nutritive virtue is not in the hand, but in the meat. —Puritan Thomas Manton, Works 13:477
