Galatians 3:10-11, 19, 22

But if you rely on works of keeping the law for salvation, you live under the law’s curse. For it is clearly written: “Utterly cursed is everyone who fails to practice every detail and requirement that is written in this law!” It is obvious that no one achieves the righteousness of God by attempting to keep the law, for it is written

Why then was the law given at all? It was given alongside the promise to show people their sins. But the law was designed to last only until the coming of the “Seed,” the child who was promised. When God gave the law, he gave it first to angels; they gave it to Moses, his mediator, who then gave it to the people.

But the Scriptures make it clear that the whole world is imprisoned by sin! This was so the promise would be given through faith to people who believe in Jesus Christ.
