For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. – Romans 6:23
…and with His stripes we are healed. -Isaiah 53:5
(S)in is like disease because it tends to increase in the man and will, one day, prove fatal to him. You cannot say to a disease, “To here shall you come, but no further.” There are some diseases that seem to come very gradually, but they come very surely. There is the hectic flush, the trying cough, the painful breathing—and we begin to feel that consumption is coming. And very soon—terribly soon to those who love them—those who were once hale and hearty, to all appearance, become like walking skeletons, for the fell disease has laid its cruel hand upon them and will not let them go. So, my Friend, as long as sin is in you, you need not deceive yourself and think you can get rid of it when you will, for you cannot. It must be driven out by a higher Power than your own—this disease must be cured by the Great Physician or else it will keep on increasing until, at last, you die! Sin will grow upon you till, “when it is finished, it brings forth death.” God grant that before that awful ending is reached, the Lord Jesus Christ may come and cure you, so that you may be able to say, “With His stripes we are healed.”
Sin is a contagious disease which passes from one to another. It is hereditary. It is universal. It is incurable. It is a mortal malady. It is a disease which no human physician can heal. Death, which ends all bodily pain, cannot cure this disease—it displays its utmost power in eternity, after the seal of perpetuity has been set upon it by the mandate— “He that is filthy, let him be filthy still.” It is, in fact, such a disease that you were born with it and you will bear it with you forever and ever, unless this wondrous prescription…shall be accepted by you and shall work in you the Divine good pleasure, so that you shall be able to say, “With His stripes we are healed.” ~ C.H. Spurgeon
