One must understand that living a faithful Christian life is essential for those who desire to be saved. Jesus said, “…No man, having put his hand to the plough, and looking back, is fit for the kingdom of God” (Luke 9:62). Surely, no one would be so naive as to think that once you become a Christian you do not have to live the Christian life.
Repentance, which precedes forgiveness of sins (Acts 2:38), means to turn away from wickedness and do what is right. Repentance demands a changed life þ a life lived for God in faithfulness. Before one becomes a Christian he should “count the cost” of what’s involved in being a faithful Christian. Jesus said, “If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. And whosoever doth not bear his cross, and come after me, cannot be my disciple. For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it? … Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand. … So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple” (Luke 14:26-28,31,32). Living a faithful Christian life is so serious, Jesus used the figure of cutting off your hand or foot or plucking out your eye in order to spare the soul from eternal damnation (Matthew 18:8-9). When anyone or anything interferes with us living a faithful Christian life and we yield to temptation and become unfaithful, our spiritual condition is then worse than it was before we became a Christian. “…The latter end is worse with them than the beginning. For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment…” (2 Peter 2:20-21). The exhortation of heaven is, “…be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord” (1 Corinthians 15:58). That demands faithfulness. Nothing short of it will do.
