In the present day society there are evidences of ethical misconducts and devaluation of ethical norms, such that, they seem useless. Consciences of some people also appear dead. Today, we see people worshipping and serving many gods with convictions in their hearts that they are worshipping the true God. People make many images for worship. They vow falsely using the name of God. Children insult and despise their parents without regret, steal and commit illicit sex with no fear of consequences. We see human beings being killed like fowls without government's concern, false witness in different quarters, and covetousness of people's property becoming the order of the day. We can also testify of lots of corruption and social vices today. This book intends to advocate the relevance of Christian ethics and its application in the present day society which is so depressing and deteriorating. The application of theonomous norms and sound conscience in every human conduct will produce agenuine morality in line with the required ethical principles and the Scriptures. Believers of Christ have the responsibility of advocating and spreading the ethical norms and values in today's society.
