This document provides a summary of key points from Galatians 3:15-20 about the relationship between God's promise, covenant, and law. It explains that God's promise to Abraham preceded the later establishment of the law by 430 years, and that the law was added not to replace the promise of salvation but to reveal human sinfulness and point to its fulfillment through Christ. While the law remains important, salvation ultimately comes through faith in God's unilateral promise, not from works of the law.
