Why Does God Allow Sickness?

October 19, 2026

Scripture does not give a single explanation for every illness. It includes a case where illness is not connected with personal sin (John 9:1–3), and a case where illness is connected with unworthy participation in the Lord’s Supper (1 Cor. 11:29–30). Believers in Scripture become ill and are not always healed; the body and creation remain subject to decay until the resurrection.

What Does the Bible Say About This?

  • The man’s blindness from birth was not the result of his own sin or his parents’ sin (John 9:1–3).
  • In Corinth, many were weak and sick, and quite a few had died; Paul connects this with unworthy participation in the Lord’s Supper (1 Cor. 11:29–30).
  • Jesus told the man who had been healed to stop sinning, so that something worse would not happen to him (John 5:14).
  • Believers became ill: Epaphroditus was sick and nearly died, but God had mercy on him (Phil. 2:25–27); Trophimus was left sick (2 Tim. 4:20); Timothy often suffered from ailments (1 Tim. 5:23).
  • The outward man is wasting away, while the inward man is being renewed (2 Cor. 4:16–18); all creation groans, awaiting release from decay (Rom. 8:20–23).

Romans 8:20–23

20 For the creation was subjected to futility, not willingly, but because of the One who subjected it, in hope, 21 that the creation itself will be set free from its bondage to decay and brought into the freedom of the glory of the children of God. 22 We know that the whole creation has been groaning and suffering the pains of childbirth together until now; 23 and not only it, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption, the redemption of our bodies.

16 Therefore we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. 17 For this light, momentary affliction is preparing for us an eternal weight of glory beyond all measure, 18 as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.
