Really? Are medical personnel a breed apart from the rest of the world so that none of them are Christians? That none of them witness to each other? That they never go to community events or even have Christian family members, and no one but sick people to speak to them about Jesus? In fact, many medical workers are Christians.

Yes, God will turn anything for our good as Romans 8:28 says, but he’s a good father, and good fathers do NOT make their children sick. When human fathers do this, they end up in jail—or worse.

“Which of you, if your son asks for bread, will give him a stone? Or if he asks for a fish, will give him a snake? If you, then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask him! Matthew 7:9-11

And we know that in all things God works for the good of those who love him, who have been called according to his purpose. Romans 8:28
