I recently preached a series of sermons at our church from the book of First John. What became very obvious as we went through the book, is the serious nature of sin and the toll it takes on the community of faith as well as the individual. Today, I want to briefly talk about the devastating effects of sin on the human body. Now let me preface my remarks by saying that I do not believe all sickness or disease is related to some sin in a person's life. We live in a fallen world and our outward man is perishing even though our inner man is being renewed day-by-day.
One of the first examples that come to mind are the believers at Corinth. In chapter 5 we read of a man who is involved in a form of gross sexual immorality. Because he (and the congregation) saw no need for repentance or discipline, Paul instructed the church to hand him over to Satan for the destruction of his flesh. Paul seems to indicate that sexual sins are particularly destructive to the human body:
1 Cor 6:18 Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.(KJV)
To this same church, he also warned that coming to the communion table in an unholy manner and a reckless way could result in premature death as well as sickness. Yet another extreme but biblical example is that of Ananias and Saphira. Their sin brought immediate physical death. John stated that he wrote his epistle so that the believers would not sin (I John 2:1). Not only does sin have eternal consequences when not repented of, but it can have devastating effects on the human body.
