We tend to treat sin more like a scrape on the knee than the cancer that it is. It seems counterintuitive to us not to do anything when we have a problem in our lives. That is, we are more prone to clean up or cover what we believe to be cuts and bruises, instead of submitting to the radical surgery that we really need.
God said to His people through the prophet Jeremiah: “Your affliction is incurable, your wound is severe. There is no one to plead your cause, that you may be bound up; you have no healing medicines” (30:12-13). The only way for sin to dealt with is to recognize we cannot do anything for it, nor do we possess anything for its cure. Rather we must trust and believe that God has carried it away in Christ so that we can justified in His sight. Only then are we healed; only then are we cured. Only then can we be truly thankful; only then can we live the life that God wants for us.
1 Peter 2:24-25 “who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness — by whose stripes you were healed. For you were like sheep going astray, but have now returned to the Shepherd and Overseer of your souls.”
