God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.
— Revelation 21:4
God can work in spite of sickness. He still answers prayer and heals people today, and He still does miracles. In sickness and in hardships, He can work in a person's life. Even if a person still has the sickness or problem, God can work in spite of it and give them a special strength. And no matter what happens to our physical bodies here on earth, we have the promise of heaven and ultimate healing in heaven. At that time, God says He will wipe away all our tears. There will be no more death, sorrows, crying, or pain (see Revelation 21:4).
What a glorious promise! There is more—so much more!—beyond this life on earth. Whatever our limitations, whatever our problems, God promises us that we will one day receive a new body that won't have the shortcomings we experience today.
And God can also use sickness to bring a person to Himself, can't He? I know of many people who have come to the Lord in the hospital or when facing death. Suddenly they reevaluate their lives. They wonder, What am I living for? What's really important in my life? What's going to happen to me when I die? And they begin to think about eternity.
As the psalmist said, "Before I was afflicted I went astray, but now I keep Your word" (Psalm 119:67). God can work in spite of sickness, and He can work through sickness. Nothing is impossible for Him.
