Why God Gave the Law & Why it Can’t Save You

God didn’t give the law to save us, but to show us our need for salvation and point us to Jesus. The false teachers in Galatia wrongly taught that faith plus law-keeping equals salvation, but Paul clarifies that salvation comes through faith alone. God’s promise to Abraham came 430 years before the law, demonstrating that promises require belief while laws demand performance. The law serves three purposes: revealing sin, imprisoning us under sin’s power, and acting as a guardian until Christ came. Jesus fulfills every promise as Abraham’s true offspring who blesses all nations. Christians should rest in Christ’s finished work rather than trying to earn God’s approval through performance.


Scripture: Galatians 3:15-25; Gen 12, 15; Rom. 3:20, 5:20, 7:7; Ex. 20:18-19, John 1:1-3, 14
