A doctor advised a relative of mine (Robert) to encourage his wife to receive chemo and radiation for her curable cancer. But Robert knew that chemo and radiation sometimes have bad side effects and people at times die from this treatment. So he proudly proclaimed, "We're just going to trust the Lord for her healing!" Well, she died, and her doctor said chemo and radiation would have cured her case. I hold Robert responsible for his wife's death! Since then, I have seen such ghastly anti-chemo Christian arrogance repeated! Similarly, when the Lord has prompted me to encourage someone to get vaxxed and they refuse, saying, "I'm just trusting the Lord to protect me," and they or their spouse die or get very sick for a long time, I'm conclude that they have committed the sin of putting God to the test.
My brother is a doctor who reads all the relevant Covid research, and so, he is militantly pro-vax. All but 3 of his many patients got vaxxed at his prompting and are Covid-free. Of the 3 who refused, one got Covid. As he told me months ago, "Tell your friends to get vaxxed or they will get Covid sooner or later." I thought this extreme, but now realize it is coming true!
