Matthew 8:3 Then Jesus put out His hand and touched him, saying, “I am willing; be cleansed.”
It is God's will for you to be healed.
In fact, Jesus always healed the sick who came to Him. The blind, lame, maimed, mute, deaf and demon-possessed - all who were sick with incurable diseases, He healed all of them! (Matthew 8:16)
The Bible says that he who has seen Jesus has seen the Father (John 14:9). And if you are wondering what God is like, just look at Jesus! He never gave sickness to anybody. You never find Jesus looking at a person and saying, "Come here. You are too healthy. Receive some leprosy!" In fact, when a leper came to Him for healing, Jesus, full of compassion, told the leper, "I am willing; be cleansed."
Unfortunately, there are some Christians who say, "It is God's will for me to be sick and there is a purpose to my sickness - it is for me to learn more humility. It is all part of His divine plan, and one day I shall know in heaven the reason why." But these same people also go to their doctors to get well. They take their medication and rest. These same people do all they can, spending tens of thousands of dollars seeking cures for sicknesses. Why do they do that if they believe that God wants them sick or is teaching them something? It doesn't make sense!
What makes perfect sense is this: God wants you well. He wants you whole. He wants you to be walking in health. His will is for you to be healed. In fact, He is so willing that He took all your sicknesses and diseases upon His own body so that you don't have to suffer them today. He allowed Himself to be beaten and scourged, so that by His scourging, by His stripes - you are healed (Isaiah 53:5).
Since He has already suffered the sickness on your behalf, why should you suffer it today?
If you are sick, know that God did not give you the sickness. In your daily readings, read about the healing miracles that Jesus did in the Gospels and see how Jesus is the Lord who heals you (Exodus 15:26). Hear His gracious words, "I am willing, be healed," and know that they are as much for you today as they were for the leper.
