If you doubt whether such description should be given, take a look at the Gospel of Mark. The very first chapter produces at least three accounts in which Christ exercises His power over physical illnesses. During His ministry, Christ healed countless people with infirmities ranging from leprosy, to fevers, to blindness and lameness. It is in the story of Lazarus, where Christ raised him from the dead that we see a glimpse of why Christ many times healed those who were sick, or had already died: “This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby.” (John 11:4)
Mark 2:1-12 declares the event of the crippled man with his friends who let him down through the roof of the house. While this story is often told with the culmination of Christ telling the man to “Arise, and take up thy bed, and go thy way into thine house” (Mark 2:11), in reality, that is only a side-note. The verse immediately preceding Christ’s command to get up and walk reveals a greater reason for why He would heal the crippled man: “But that ye may know that the Son of man hath power on earth to forgive sins…” Christ proved that He does indeed have power to forgive sins—that He is God!--by the very visible act of making to walk he who could not walk.
Today, God does not necessarily heal physical illnesses in the same way that Christ did during His ministry on earth. However, we can be certain that He still acts in such a way that it is His best for that person…even if sometimes we do not understand His ways. Keep trusting in His goodness!
