When I started walking with the Lord, I was told by older Christians that we weren’t under the law but under the grace of God. So, I didn’t read the old testament. The law is an eye for an eye, a touth for a touth and a life for a life. The law is the knowledge of sin. The law had to be established to set a standard for believers. But the law was established by the blood of Jesus Christ, who was judged by the law and found to be perfect. He was the perfect sacrifice, which satisfied the law. It was God’s plan so we could enter in the kingdom. For there is none righteous, no not one. We have all gone astray, dead in sin. But the blood of Jesus Christ redeemed us by faith in God. Not by the will of man, but by the will of God and faith in Jesus Christ that we have redemption from sin. In doing so, we establish the law in our hearts.
