I recently read an article that the anecdotal evidence that the 2017-2018 flu season has been one of the worst in recent memory is backed up statistically. As I thought about this, it brought to mind the many lessons that illness can teach us. Illness, whether it is caused from outside our bodies or inside our bodies, reminds us that Creation is fallen and it groans under the weight of sin (Rom. 8:22). For Christians, illness causes us to groan and to remember that this is not our permanent home (2 Cor. 5:1-4). Moreover, it causes us to long for our permanent home where God will remove all the effects of the Curse (Rev. 21:1-4). Beyond these lessons though, God reminded me of how illness instructs the way we evangelize. In his book Practical Religion, J.C. Ryle spends an entire chapter writing about Sickness and highlights the fact that illness is a reminder of death. He notes that most, including too often us Christians, live as if they were never going to die. But the author of Hebrews reminds us “it is appointed for men to die once and after this comes judgement” (Heb. 9:27). To most our age death is a distant thought, something to be dealt with in 50 or 60 years but our Lord reminds us in Luke 12:20 that we do not know when God has decreed our deaths. For some it will be very soon and for others it will be in many years. And illness, Ryle writes, awakens us from our day-dreams and reminds us that we have to die as well as to live.
