It just shows the unmitigated ego of Rosie and this author.
He would usurp God’s power and judgement, while limiting God’s power to his own understanding and apologize for God by making excuses for God’s lack of working through him.
I can guarantee that God is not making excuses and I know that God can heal you wherever you are and wherever your heart is.
I guess Paul wouldn’t change his life either.
He often doesn’t heal because he wants you to learn something through the illness, usually something of Him. His grace has certainly been sufficient through mine. I’ve learned more about Him being sick than I ever would have being well. It’s called dependence, for one thing.
