First, let us determine whether sickness is bad or if it is a "blessing in disguise." The answer should be obvious to any rational person. Sickness is bad. It is not a blessing in disguise. It looks like a curse because it is a curse, not a blessing wrapped up to look like a curse. Were it not for religious but Biblically clueless ministers, no one would ever believe that sickness is a friend or a blessing in disguise. You certainly won't after you see what God says about sickness:


Sickness is bondage to the devil.

Luke 13:16 speaks of a woman who could not lift herself up for 18 years:
"And ought not this woman, being a daughter of Abraham, whom Satan hath bound, lo, these eighteen years, be loosed from this bond on the sabbath day?"


The devil bound her. Jesus loosed her.


Sickness is oppression of the devil.


Acts 10:38:

How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil, for God was with him.

The devil oppressed the people. Jesus healed them.


Sickness is captivity.


Job 42:10:

And the Lord turned the captivity of Job...

Job's trials, which most notably involved sickness, are called captivity. We know that Satan, not God, put all of Job's sicknesses on him.


Sickness is a curse.

In passages too numerous to mention, most notably Deuteronomy 28:15-68, sickness is called a curse.

John 10:10

According to this verse, it is the devil, not God, who steals, kills and destroys. Jesus came to give abundant life, not abundant death or abundant sickness. Sickness takes away from the abundance of your life. It also steals your time (and often that of others who must care for you) and sometimes destroys your bank account in the process. No one but a detached theologian would ever say that being unable to lead a normal life because of sickness is "abundant life."


1 Cor 5:1-5

In this passage, a man is to be turned over to Satan for the destruction of his flesh. Therefore, Satan, not God, must be the one who destroys flesh. If God were going to do it himself, there would be no need to hand the man over to Satan.

When God renovates the earth, there will be no sickness on it. He also says that there will be no curse. Sickness and the curse on the earth because of sin go together. In the future, there won't be any sickness to get! If God were the author of sickness, we would expect it to be around throughout eternity.

Based on these verses, you can see that Satan is the author of sickness and God is the author of healing and health.
