One of the vital foundations of our faith is that salvation is by grace through faith, “not of works, lest any man should boast.” (Ephesians 2:8-9) Paul clearly makes that point in the epistle to the Galatians. It is through faith in the risen Jesus that we are forgiven and justified in the sight of God; something that the law of Moses could never do (Acts 13:38-39).
The law contained pictures and types of the Lord Jesus Christ. This is beautifully recorded throughout the Book of Hebrews. But as holy and wonderful as the law of God is, it could not save a single soul, because to be just before God according to the law required absolute, sinless perfection, with no room for error, ever! (James 2:10,11) Hence, the law served as a schoolmaster that leads a person to the saving grace of God in the Person of Jesus Christ (Galatians 3:24-26).
No amount of good works can satisfy the just demands of a holy God. Only the spotless Lamb of God can and did do that on our behalf (1 Peter 1:18-19).
“… Behold the Lamb of God who takes away” our sin (John 1:29)!
