Heaven is wonderful, but this life on earth is far from "good", but it is not meant to be good, so it is challenging. Life is not that "good" for most people and if you get involved in helping people through this life, you share in their hard times which is not "fun", but is rewarding.
I'm not going to attribute it to all Christians, but many believe that God has Munchausen by proxy.
He got the disease from natural law and God supernaturally brings good out of the bad, spiritual growth that will eventually help destroy evil forever.
Yes, read Romans 8:28
By befriending a believer and helping them you may learn to be saved and go to heaven but at the very least you can end up in the better parts of hell, but those that mistreat believers will go to the worst levels of hell besides the temporal judgements of the human criminal justice system that you may face.
ah, your God is fine with a christian suffering in the ICU.
No, He is against it but sometimes it is necessary. Generally If you live according to God's moral teachings you will probably not ever be in an ICU.
No, see above He would prefer that no one end up in the ICU.
If you do good just to get rewards you are probably not a Christian. Christianity is all about God, not us. But of course, since all humans are created in His image, by helping others you are glorifying God. You should do good because you love God not to get rewards.
So the man in the ICU in the OP was getting what he deserved? If he was a good Christian he probably would not be there?
Can god not spiritual grow someone that does not involve pain and suffering?
No, we all deserve hell. Apparently God felt he needed to suffer to grow spiritually, everyones growth is different and requires different things. Even great Christians suffer, Peter was crucified up side down and he was one of the greatest Christians and Paul was put in prison and eventually executed. I am referring just to a general principle that even applies to non Christians. If you obey His moral laws you are less likely to suffer.
Well there are many of God's laws that would help protect you from many different diseases. As far as COVID, God commands us to generally obey the government authorities so you should do what the experts say to prevent exposure. In addition, treating your body like the Temple of God as the bible says should cause you to eat healthy and not engage in unhealthy behaviors like smoking and drug use. And it should encourage you to exercise. Then obeying His laws about sex will prevent you from engaging in promiscuous sex thereby preventing you from getting STDs. Also, Christ's teaching about not living a life of violence will help avoid the ICU. All of these teachings can help prevent you from ever ending up in an ICU.
