Why do we (I used to propagate this lifestyle) teach the Law as a set of standards by which we must attain too? What is the true purpose of the Law? Jesus fulfilled the Law (Matthew 5:17). And once the Law was fulfilled, His very first teaching after Calvary was alongside a road to Emmaus.
And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself. Luke 24:27
Jesus’ own example was to fulfill what we cannot and then afterwards He explained the Law and prophets all spoke of Him. Jesus taught before Calvary (the fulfilment of the Law), “Which of you by [(Greek: merimnao) desire to promote one’s self] can add one cubit unto his stature? (Matthew 6:27), pointing out that God cares for us and He provides for us, not only natural but spiritual needs as well.
When we approach the Law by natural attempts to understand and attain to, we fail from intent long before action even begins.
John saw what was happening at the cross when Jesus was crucified. He was an eyewitness to Jesus’ death. A few moments before His death Jesus declared, “It is finished!” (John 19:30). It is one word in the Greek and can be translated, “Done!” “Finished!” or “Completed!” The entire redemptive work of Jesus Christ was finished. The Son gave His report to the Father in a loud voice so all mankind could hear it, and then He went home to the Father having completed the Father’s will.
Jesus did not say, “I am finished.” In essence He said, “It was finished and as a result it is forever done.” “It stands finished.” “Done.” The idea is that of perfection, accomplishment, relief, satisfaction, and victory.
All the accumulated sin, and guilt, of all men, of all time, guilt of all time, including the combined hells of all who have offended God, was paid in full by His death.
The death of Jesus Christ completed the redemptive work. The Lamb of God has made His great sacrifice for the world. It is this that is now done. Our great Substitute paid the great ransom, paid it to the uttermost cent. “It is finished” indeed! There is nothing that can be added to the atoning sacrifice of Jesus Christ.
Our atonement was completed in the moment of Christ’s death for our sins. All of the righteous demands of the law of God against our sins were paid in full and satisfied in His sacrifice for sin. The punishment of our sins and the satisfaction of the righteousness of God meant that God was now free to offer the believing sinner His own perfect righteous standing before God based upon grace alone (2 Cor. 5:21).
At the heart of the death of Jesus Christ is our atonement. The payment was paid in full. God declared, “It is finished!” You and I can never make satisfaction for our sins, no matter how good we may think we are. You and I can never contribute to our salvation in the least degree. “It is finished!” We cannot add in the least or the greatest thing to His finished work. You cannot atone for your sins committed before or after baptism. You cannot atone for your “temporal” sins. You baptism will not save you. Only God can forgive sins. Only the death of the perfect Lamb of God can cover your trespasses against God. The moment you add one thing to the finished work of Christ you destroy it. To require the sinner to contribute to his own salvation in some measure only contributes to his eternal state of being lost.
The satisfaction of Christ is the only satisfaction for sin. The perfect sacrifice of Christ is so perfect and final that it leaves no possible liability for any sin of the believer.
We are to believe on the finished work of Christ. He is our righteousness. Jesus Himself taught this on a roadside to Emmaus.
