THE PRACTICAL USE OF SAVING KNOWLEDGE,
Contained in SCRIPTURE, and holden forth briefly in the foresaid CONFESSION OF FAITH and CATECHISMS.
THE chief general use of Christian doctrine is, to convince a man of sin, and of righteousness, and of judgment, John 16:8. partly by the law or covenant of works, that he may be humbled and become penitent; and partly by the gospel or covenant of grace, that he may become an unfeigned believer in Jesus Christ, and be strengthened in his faith upon solid grounds and warrants, and give evidence of the truth of his faith by good fruits, and so be saved. The sum of the covenant of works, or of the law, is this: ” If thou do all that is commanded, and not fail in any point, thou shalt be saved: but if thou fail, thou shalt die.” Rom. 10:5. Gal. 3:10,12. The sum of the gospel, or covenant of grace and reconciliation, is this: ” If thou flee from deserved wrath to the true Redeemer Jesus Christ, ” (who is able to save to the uttermost all that come to God through him,) thou shalt not perish, but have eternal life.” Rom. 10:8,9,11. For convincing a man of sin, of righteousness, and of judgment by the law, or covenant of works, let these scriptures, among many more, be made use of. ~Taken from the Sum of Saving Knowledge https://www.semperreformanda.com/creeds/the-sum-of-saving-knowledge/
