My step-brother has been recently diagnosed with an aggressive form of leukemia. The doctors tell him with out treatment he will die. He is claiming “If it’s God’s will, God will heal him” and so he thinks he doesn’t need any treatment. Can anyone help me find verses to show him that refusing medical treatment isn’t scriptural? I mean wasn’t Luke a doctor? And there certainly aren’t any verses saying you should refuse treatment. I know this isn’t probably the right place to post this, but you guys seem to know your way around the bible pretty well.
There aren't any verses in Scripture that say that refusing medical treatment is against Scripture! But my immediate thoughts on this are:
1/ Paul's travelling companion, Luke, was a doctor (Colossians 4:14).
2/ Paul and some of his other co workers sometimes got sick, (Galatians 4:13; 1 Timothy 5:23; Philippians 2:26-27). We are not told that Luke treated them, but we are not told that he didn't.
3/ I would not want to restrict God by telling him that he can't heal through the medical profession. There are doctors, nurses, technicians, physios etc who are Christians and they do their best to serve God with the gifts that he has given them, just as much as anyone else does. Your brother may meet some, if he decides to have treatment. Or he might meet other people who are being treated who do not know God, and this will be a chance to share his faith with them.
4/ If receiving medical treatment was wrong or anti Scriptural, I do not think there would be any Christians working in this area - especially not hospital chaplains - and no Christian leader would ever have been to the doctor's for anything. But this is not the case. I understand that Joyce Meyer has had breast cancer which was treated with surgery.
It could be that your brother is in denial, and saying "oh, God will sort it out" is easier than facing it/asking questions/dealing with his emotions. If it were me, I think I would pray, commit the matter to God and then go ahead with treatment until or unless he told me otherwise.
Praying for both of you.
