The Book of Job establishes the reality that Satan can be the source of sickness and that sickness can be caused by his attack on our lives. Satan aka "Lucifer" is the most powerful being created by God.
Job also shows us that Satan can influence the weather and cause string winds, storms and other phenomenon. (Does he do so today?)
And at the same time our sin natures are expressed in our bodies through debility which results in old age and death.
Paul called Timothy to “rightly divide the word of truth” 2 Timothy 2:15b(KJV), and we are called to do the same. God can cause something to happen directly or indirectly, through secondary causes such as men or an animal or insect etc..
Acts 12:23 23 Immediately an angel of the Lord struck him down, because he did not give God the glory, and he was eaten by worms and breathed his last.
God keeps Satan under his control and will often use him to accomplish his purposes. This was the situation with Job, Satan had to get permission from God to go attack Job.
and then Job said it was the Lord who had “taken away” the sickness and misfortune. And the writer says he “did not sin or charge God with wrong” even though Satan was more immediately involved in the wind that blew down the house that killed the kids (Job 1:18–22).
And in 2 Corinthians 12:7, Paul says, “To keep me from becoming conceited because of the surpassing greatness of the revelations, a thorn was given me in the flesh, a messenger of Satan to harass me” — but what was the purpose of the thorn? — “to keep me from becoming too conceited.” So the question is does Satan want you or me not to be conceited? No, God wants him not to be conceited. Satan is the instrument that God is using in this thorn to keep Paul from sinning. If you have a thorn, Satan could be designing your sin, yet God is designing your sanctification. So we can see Satan is one of God’s instruments in causing things to happen.
Starting with Adam & Eve and the Fall in the Garden of Eden, sickness entered into the world as part of the curse of sin. Scripture ultimately directs us to deal with sickness through our prayers of faith in which the Holy Spirit must give discernment. James 5:14-16 gives us instructions for sickness in general, it says; “Is any sick among you? Let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith will save the sick and the Lord will raise him up; and if he have committed sins they shall be forgiven him.” God also instructs us to be wise and of course wisdom will point you to health care which God has also graciously provided to us.
The New Testament tells us that Christ healed sicknesses such as leprosy, blindness, and paralysis, but in those contexts made no reference to Him casting out devils. The early disciples were instructed to “lay hands on the sick and they will recover.” We as believers should realize that if we must study the Bible as a complete work, the Bible balances itself out. This will keep and protect us from building doctrines, positions, or movements on “pick and choose” scriptures taken out of context by supposed “special revelations from the Lord”. It will also help us to understand how God uses natural means like doctors and medicines to deal with naturally occurring sickness and disease. Equally important is that He also uses the “name of Jesus” spoken in spiritual authority to deal with demonically inflicted illness!
Are we sick from Covid because of a Satanic attack on the world?
God takes our freedom seriously and his judgment on sin is to allow us to experience the wages of our sin. God's judgment has a remedial purpose for those who listen as well. God’s desire is always that WE his children turn back to him and be healed and restored. “For I have no pleasure in the death of anyone, declares the Lord God; so turn, and live” (Ezekiel 18:32).
Scripture also makes it clear that we are not to judge others, because human beings are so interconnected in life, the innocent will often suffer along with the guilty.
Jesus explained this in regard to two disasters of his own time: a political massacre in which some Galilean Jews were killed and a building accident:
“Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered in this way? No, I tell you; but unless you repent, you will all likewise perish. Or those 18 on whom the tower in Siloam fell and killed them: Do you think that they were worse offenders than all the others who lived in Jerusalem? No, I tell you; but unless you repent, you will all likewise perish” (Luke 13:1-5).
Our lesson is a large-scale disaster (such as Covid) is therefore not a reason to condemn others. Whatever disaster befalls us is a call to examine our own lives and get right with God, making us aware that none of us knows how much time we have left on earth.
