Denise,
Perhaps some of the physical problems your husband is having may be due to having both the chemotherapy and immunotherapy. Sometimes it can be too much on your body even if it's supposed to be good for you. Maybe he just needs to give his body a rest for a while. You are right about only God knowing when we die. My husband quit having chemotherapy and immunotherapy and even refused anymore CT scans since they accidentally gave him the wrong medicine and it affected his memory for a while. However, he also lived 14 years with cancer and no treatments. I think it was an answer to all of our prayers.

It's too bad that your husband only believes in God and not Jesus but it's good that at least he believes in God. Don't feel like your husband is going to hell. God is a loving and forgiving God. He understands what your husband is going through now and why he is thinking like he is. God knows that your husband is ill and probably very frightened. What you need to do now is what us Christians are supposed to do and that is pray for your husband. Ask God to help your husband believe in Jesus and that he is the savior. Put everything in God's hands and just have faith. It will work.
I wouldn't call in the pastor. Sometimes they can just be irritating to people who are questioning the Bible. Your poor husband doesn't need anymore stress in is life. He's dealing with enough.
I will continue to pray for both of you also.
