The challenge of the Christian life is to keep the life fresh and alive and new.  This life is a life of living and walking in the Spirit and living and walking by faith.  We received the Spirit by the hearing of faith and God wishes for us to continue to draw from Him by faith and living by the Spirit.  The tendency for the church has always been to go back to following rules and rituals rather than moving in the Spirit because in some ways it is easier and more familiar to do what you have always done in the past.  The problem of going backwards is the problem of creating a dead church, one in which there are few, if any, miracles and few, if any, conversions.  Religion reduces the life to rules and regulations, praise and blame, rewards and punishments.  Instead of people moving in the Spirit, people follow laws and regulations which do not have any life in them.  If we choose to follow the law, we will live but we will not produce a dynamic Christian life.
By the law is the knowledge of sin and the strength of sin is the law. When we receive the anointing and the anointed one we no longer need a schoolmaster, we need to walk in the Spirit.  The law brings condemnation or conceit.  The Spirit brings freedom.  If we choose to live by the law, we will never be free.  We will always be judged, good or bad, or right or wrong.   But if we live in the Spirit, there is liberty and freedom…no condemnation, no judgment, no sin.  There is spontaneity and openness and a real sense of reality.  People who live by the law do not have a grasp of reality but are bound by their own judgments of fairness.  That produces people who are hard and cold and rigid, who live by concepts not by love.
People who go back to the law make justification a matter of their own ability to keep the law, self-righteousness, and not justification by faith in Christ, his life, death, and resurrection and sending of the Spirit.  This leads to denominations and religions and segregation rather than a universal church with no respecter of persons open to all people of any background or denomination.

The law makes nothing perfect but the bringing in of a better hope did by which we draw nigh to Christ.
Heb7:19


The law makes nothing perfect but living and walking in the Spirit is the end of the law for all who believe in Christ.  The Spirit perfects us as we do not our own will but the will of God.  The letter of the law kills.  It is the Spirit that gives life.  God is the law giver in the old covenant but in the new covenant, God is the Christ giver.  It is the difference between the natural and the supernatural, the natural and the spiritual.  It is the difference between life in this world and eternal life.  It is the difference between being dead in our sins and trespasses and being alive in the Spirit.  Why would any want to go back to the law? They would, only if they refuse to continue their journey of faith and want to live in the security of the past.  Do not draw back.  Do not begin in the Spirit and end up in the flesh.  Follow the Spirit and live by faith.  The just shall live by faith...not by the law.
