Luke 10:26
ESV - 26 He said to him, "What is written in the Law? How do you read it?
Ben, you asked a good question! God used the law such as His desire that we love Him with all we have and love our neighbor as ourselves! Pretty hard to do. In fact, impossible! But God uses the law to show us that, and thus our need of Him, of His help, etc. Romans 3:20 says, “Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.” King James Version (KJV) The law doesn't and can't save us (Gal. 2:16, which says, “Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.”) King James Version (KJV)
