The Bible does not specifically link physical healing with spiritual healing. Often times people are physically healed when they place their faith in Christ – but this is not always the case. Sometimes it is God’s will to heal, sometimes it is not. The Apostle John gives us the proper perspective: “This is the confidence we have in approaching God: that if we ask anything according to His will, He hears us. And if we know that He hears us – whatever we ask – we know that we have what we asked of Him” (1 John 5:14-15). God still performs miracles. God still heals people. Sickness, disease, pain, and death are still realities in this world. Unless the Lord returns in the next 50 years or so, almost everyone who is alive today will die, and the vast majority of them (Christians included) will die as the result of a physical problem (disease, sickness, injury). It is not always God’s will to heal us physically.
Ultimately, our full physical healing awaits us in Heaven. In Heaven, there will be no more pain, sickness, disease, suffering, or death (Revelation chapter 21). We all need to be less preoccupied with our physical condition in this world, and be a little more preoccupied with our spiritual condition (Romans 12:1-2). Then, we can focus our hearts on heaven and when we will no longer have to deal with physical problems, Revelation 21:4, “He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away.”
