For this, Thou shalt not commit adultery. A Christian cannot read the New Testament and believe that Christians are not under the same moral responsibilities under Grace as in any other dispensation. The difference is that now, by faith in the cross, we have Christ living within with His resurrection power and spirit of holiness empowering us to live within and above the requirements of God's commandments. There is only chaos where there is no obedience to the laws of God. The absence of confusion and chaos.
Obedience produces order and orderly behavior replaces all chaos.
We have removed the last obstacle to achieving happiness. We have destroyed chaos until we have caused all conflict to cease. Conflict and chaos are first cousins. We have moved within close range of happiness when we have come out of chaos and entered a life of perfect order which only loving obedience to God's Kingdom laws can produce. We will never know the first thing about God as a true and loving friend until we come to the full realization that He wants man to be happy.
