A word to us from J.C. Ryle on John 5:1-18, the healing of the paralytic (emphases in bold are mine):
Every sickness and sorrow is the voice of God speaking to us. Each has its peculiar message. Happy are they who have an eye to see God’s hand, and an ear to hear His voice, in all that happens to them. Nothing in this world happens by chance.
And as it is with sickness, so it is with recovery. Renewed health should send us back to our post in the world with a deeper hatred of sin, a more thorough watchfulness over our own ways, and a more constant purpose of mind to live for God. Far too often the excitement and novelty of returning health tempt us to forget the vows and intentions of the sick-room. There are spiritual dangers attending a recovery! Well would it be for us all after illness to grave these words on our hearts, “Let me sin no more, lest a worse thing come unto me.”
Let us leave the passage with grateful hearts, and bless God that we have such a Gospel and such a Savior as the Bible reveals. Are we ever sick and ill? Let us remember that Christ sees, and knows, and can heal as He thinks fit. Are we ever in trouble? Let us hear in our trouble the voice of God, and learn to hate sin more.
