Some time ago, the concept of the “carnal Christian” became popular among some evangelical groups. The basic idea was that someone could be saved, and yet living no differently than an unbeliever day after day. In their lives there would be no hunger and thirst for righteousness, no patterns of obedience, little or no prayer or Bible reading, spotty church attendance, coupled with a love for the world, and a worldly mindset hostile to the Christian faith. Yet, because these people had “prayed the sinner’s prayer” or gone forward at a Billy Graham rally, or “asked Jesus into their hearts” at a youth camp, they were supposedly Christians. This shallow idea of conversion was coupled with the biblical concept of “once saved, always saved,” and a poisonous concoction resulted. Once that concoction was downed, the person became seriously ill with spiritual self-deception. The end of that road is hell. If anything gives you complacent comfort in a sinful lifestyle, it is a devilish component of the problem.
