I wish I knew what to say.. But daddy IS saved, no amount of temporary wavering faith can change that. God is bigger than this cancer, bigger than daddy's fear and doubt. And when this is all over, he WILL be a stronger Christian for it.
I flip flopped between emotions too. What if they find more than they think is there? What if they find they can't operate? What if it comes back? What if I lose faith entirely because God allowed this to happen to ME, a non smoker, instead of my sister who smokes like a chimney? Why is this happening to me when I have enough **** to deal with already? Who will take care of Tequila if I die?
To put things bluntly, daddy needs to develop a kick-ascot attitude right now. LOL... Cancer will not beat him, the devil cannot defeat him no matter what. God is on his side, and he will be fine.
