We have separated sin and sickness from each other.
Sin and sickness are both connected in Scripture, as well as disconnected. For example Epaphroditus was very seriously sick -- "nigh unto death" -- but definitely not because of sin. Many Christians have sicknesses and physical disabilities even though there is no reason to believe it is due to sin.
As to why we get sick, it all goes back to the curse that came upon creation through the disobedience of Adam. Sickness became a part of the human condition. Thorns and thistles were complemented by viruses and pathogenic bacteria.
Up until very recently, medical professionals were generally honorable and also honored their Hippocratic Oath. However when Big Pharma began making huge profits from pharmaceuticals, it also corrupted many doctors. Medical ethics were compromised for the sake of cash, and so when we come to coronavirus, it went even one step further. Treason as well as cash were involved in the creation of biological weapons, with American and Western public health officials actually helping and financing the Chinese Communist Party to create biological weapons in Wuhan which would eventually be used against the West.
The release of Wuhan virus (which originated with Chinese military intelligence )was an act of war.
And it succeeded beautifully because the public health officials in the West and in the WHO were committed to protecting China and destroying their own countries.
The Western media should have been in the forefront of exposing this criminal conspiracy. Instead they became co-conspirators by daily publishing bogus reports, creating fear and panic, and attacking HCQ.
It is now clear through hard evidence from epidemiologists that the lockdowns were worthless, masking was a joke, and social distancing was meaningless (as you can see from the Biden hysteria).
HCQ was deliberately sabotaged by public health officials in order to increase the number of deaths, so that fear-mongering and panic would prevail.
So instead of restoring conditions back to normal since July 2020, almost all Western nations decided to used COVID 19 as a weapon against their own people, in order to control them and take away their freedoms. These so-called "second waves" are all bogus, since the reporting of COVID19 itself is being manipulated. Just recently a NHS nurse in England resigned and told the public that medical personnel were being forced to deceive the public about this scamdemic. There were only 3 patients in 3 hospitals. We also know that at the height of the panic in the USA Trump sent hospital ships post haste to New York and Los Angeles, and they sat there vacant. The field hospital set up in Seattle for this scamdemic was dismantled since there were no patients!
