The observation of today's Christians reveals behaviors that are in opposition to new life in Christ. Christians suppose to be children of God, an epitome of spiritual essence, demonstrating some attributes of Christ- like character. I see the contradiction in some of us Christians, the level of bigotry and hypocrisy. Yet there is a basic calling, that Christians live a life that is worthy of God, who has called us into perfection (1Pet. 2:9). This book touches many areas concerning Old behavior, the two factors affecting it i.e. The Adamic nature, and the nature and power of sin. The book touches examples of peculiar human characteristics and behaviors. Seven of the manifestations of the Adamic nature and sin in man Anger, Covetousness, Fornication, Deceit, Idolatry, Unforgiving, and Pride will be treated to an understandable level to show, how every sin stands as a root for other sins. Hence, the need to put on a God's kingdom traits, something completely new, as a way to helping twenty-first century Christianity, to again, find the acceptable truth of God.
