Romans 8:2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. Paul in other verse of the bible wrote that, the christ has abolished the the old covenant with all her ordinances and requirements. Ephesians 2:15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; This law of sin and death definitely refers to the one that has being abolished. Why then, is it call the law of sin and death? It is called the law of sin and death because the flesh takes advantages of the law to work out more sin, so those who want to work righteousness through the law of commandments find themselves working out more sin although they are sincere. The law of the spirit of life in Christ, is in agreement with our new nature, unlike the law of commandments that is against the Adamic nature. The law of the spirit is embedded in the nature of the regenerated man. When we walk in the spirit we walk in that law, the result is that we will not be under the law but a fulfillment of the law. That law speak of the reality of our new birth, To walk in the spirit we have to first of all mortify the deeds of the flesh, which means to deaden it or to shut it down, as new creatures in Christ we have being empowered to mortify our flesh, because we died when Christ died and rose when he rose, that reality is already programmed in our new nature in christ. Most Christian do not fully recognize, the power of their salvation in Christ, salvation is not dying and going to heaven, it is far more than that, In fact the bible didnt say we will spend eternity in heaven. Heaven is not our final place, It is the new earth that is our final home! Take a look at this, There is a new heaven and new earth coming, for you to be part of it you have to be a new creature. However, for you to be a new creature you have to be part of the new covenant!. What do you notice in all of these? New! New!! New!!!. This current world is old, just as the old covenant passed away, so this old earth and this old human race will pass away. The law of the spirit of Christ works by faith! It is very important to note this.
