The believer in Christ is instructed to watch his/her lifestyle and doctrine in order to ensure that you save yourself and those who follow you in the final analysis at the judgment seat of Christ.
The foundations for effective lifestyle and doctrine are subscription to the Gospel of Christ, the Culture of Christ and preeminence of Christ over all things visible and invisible and His Church.
To be effective disciples of Christ we must live the crucified lifestyle in Christ and as God's Chosen people to offer spiritual sacrifices acceptable to God through Christ.
The Book highlights the consequences of false doctrines and lifestyles.
