In the Old Testament God authorized the shedding of animal blood for the forgiveness of sins for the Jewish Race. But,the Old Testament was not perfect.In fact,Hebrews 10:4, says that,"it is not possible that the blood of bulls and goats could take away sins. Therefore, God the Father, sent His only begotten Son, Jesus, into the world. When Jesus was crucified, He shed His precious blood for the whole world. Because of  what Jesus has done for us, the whole world has the opportunity to recieve Gods salvation.                                                                                                                              John 1:10-14,"Jesus was in the world and,the world was made by Him, and the world knew Him not. He came unto His own and His own received Him not. But as many as would receive Him, to them gave He the power to become the sons of God, even to those who believe on His name: who were born not of blood,nor of the will of the flesh, nor of the will of man, but of God. And the Word was made flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.It is also important to see how the bible refers to Jesus as the Word of God.Phillipians 2:16,refers to Jesus as the Word of Life. 1John 1:1 also refers to Jesus as the Word of Life. John 6:63 says,"It is the Spirit that gives life; the flesh profits nothing.The words that I speak to you are spirit, and they are life. In James 1:22, it tells us to become doers of the word, and not hearers only.You see as we become doers of the word, the word becomes the Living Word. James 1:25 says, that he who looks into the perfect law of liberty and continues in it, and is not a forgetful hearer but is a doer of the work, this one will be blessed in what he does. And this Is truely what Jesus wants of us.
