The themes connecting Galatians to the Old Testament center around the law vs. grace: the inability of the law to justify (2:16); the believer’s deadness to the law (2:19); Abraham’s justification by faith (3:6); the law bringing not salvation but God’s wrath (3:10); and love, not works, fulfilling the law (5:14).
Dhamira zinazounganisha Wagalatia kwa Agano la Kale zililenga kwa sheria dhidi ya neema: kutokuwa na uwezo kwa sheria kuhesabiwa haki (2:16); ufu wa muumini kwa sheria (2:19); Ibrahimu kuhesabiwa haki kwa imani (3: 6); sheria haileti wokovu bali ghadhabu ya Mungu (3:10); na upendo, si matendo, hutimiliza sheria (5:14).
