A sinner who accepts Christ begins the process of dying more and more to sin and living more and more to God. If some one claims to believe in Christ and yet remains morally unchanged, that person's faith is bogus. In becoming a Christian, then, there is more involved than a mere change mind. There is a change of heart which God alone can accomplish. Christians declare this truth out of a love for God and concern for their fellow man.
Truth is by definition narrow.
See also my article on Truth Decay . Jesus was crucified with two thieves, and one of them admitted his guilt. If the reader has made this his plan for life, however, that is a very foolish plan. More importantly, a person who trifles with God in such a manner is hardly likely to be able to summon a sincere repentance and faith. Such a heart will only harden through the years, and die estranged from God.
