According to individuals like Kenneth Hagin, Frederick K. C. Price, and others, God's wants us healthy all the time.
“You have a covenant with Almighty God, and one of your covenant rights is the right to a healthy body.” --Kenneth Copeland
“He promises to heal all--every one, any, any whatsoever, everything--all our diseases! That means not even a headache, sinus problem, not even a toothache--nothing! No sickness should come your way.” --Benny Hinn
But I disagree.
1. Epaphroditus was ill, and the fact that he, this minister of God, was healed was an act of "mercy" and not because health was his divine right (Php 2:27).
2. Paul doesn't rebuke his frequently ill co-worker Timothy for his lack of faith, but offers him some medical advice instead: "Stop drinking only water, and use a little wine because of your stomach and your frequent illnesses" (1 Tim 5:23).
3. "I left Trophimus sick in Miletus" (2 Tim 4:20). Paul healed many (Acts 19:11-12; 28:8-9). Why didn't he heal Trophimus?
4. For that matter, why didn't he heal himself of the famed "thorn" (2 Cor 12:7-10)? Oh, because God didn't want to heal him. So are we to conclude Paul was deficient in the faith department? I don't think so.
5. Faith healers get sick and die. Kenneth Hagin is dead, and so is Hobart Freeman, to name a couple.
6. Consider the phenomenal ministry of Joni Eareckson Tada, and it all stems from her diving accident and subsequent paralysis.
7. Steve Brown has suggested a theory that every time an unbeliever gets cancer, God allows a Christian to also get it, just to show the world the difference.
8. David, the man after God's own heart, Abraham, the friend of God, and Moses, the man who spoke with God face-to-face, are all dead. (But truly they are very much alive in the presence of God.)
9. Suffering and illness are some of God's most powerful tools in the maturing of his people. "Religious contentment is the enemy of the spiritual life always. The biographies of the saints teach that the way to spiritual greatness has always been through much suffering and inward pain." (A. W. Tozer, The Divine Conquest 124-25)
