I am a Cristian, from a Catholic background. I believe God created the universe as an ecosystem. This ecosystem has evolved an continues to evolves. We, as Gods creations, have also evolved and continue to evolve.
As part of this ecosystem, the world has imperfections and hence we have earthquakes, droughts, fires, diseases etc. because that is the nature of the ecosystem He created. I believe that God has influence over nature/ the ecosystem, but doesn't control every minute detail of it.
For us humans I believe God gives us free will to love him or not. Again, i believe God does not control every minute detail of our bodies and lives, hence will suffer disease, pain and disabilities. This is not because God so punishes us as individuals or inflicts his wrath on anyone ... it is how the ecosystem in God's world works.
I know some "Christians" have a very different view of the same God by reading the same scripture and interpreting it differently. I definately dont believe in pre- destination - the idea that God created a small number of "His People" destined to heaven ... and therefore the remainder He created as destined for hell and suffering. I dont believe every disaster or suffeting is inflicted on us as revenge for some individual sin (for example natural disasters attributed by some "Christians" because of Gay Pride matches or not praying enough).
There is no magic proof you will get to prove or disprove there is a God ... otherwise the argument would have been settled millenia ago!
Ultimately, I know I can't see or understand this from Gods view and some / all if it will remain a mystery. This is where faith / belief comes in.
However, Covid19 or any other natural disaster does not conflict with my belief in God, His kindness and His love.
