In the medical field some diseases have been designated as the "silent killers" because they gradually consume you without causing any serious symptoms in the early stages. Imperceptibly, they do their damage before the problem is even diagnosed. Some of these "silent killers" are hypertension, high cholesterol, diabetes, heart disease, lung cancer, and colon cancer. Because of their "silent" nature, it is important to have regular medical examinations in order to diagnose a problem before it is too late.
Just as there are some "silent killers" of our physical body there are silent killers of our spiritual life as well. They do their insidious work almost imperceptibly until they destroy a meaningful relationship with God and our fellow man. They ruin our happiness and joy as Christians and render us ineffective in our service to God. They generate a cynical and critical attitude of just about everyone and everything around us, our family included.
Among these "silent killers" of our spirituality is ENVY. Solomon described envy as the "rottenness of the bones" (Prov. 14:30). This insidious killer of the spiritual life eats away at the heart and makes it impossible to have good will toward your fellow man.
Another is JEALOUSY. This killer is closely akin to envy. Paul said, "For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way?"(1 Cor. 3:3, ESV).
LUKEWARMNESS is so despicable before God that he will spit out of his mouth those who are afflicted with this dreaded killer (Rev. 3:16). Silently, almost imperceptibly, it does its disastrous work.
MATERIALISM is so insidious that it convinces man that in his pursuit for earthly gain, he is serving God.
We would be wise to consult the Great Physician and examine ourselves (2 Cor. 13:5) lest we let these silent killers of the soul destroy us now and in eternity.
