A faith-filled but very careful look at miraculous healing. In differing from some of the "proto-televangelists" of his day (he was a contemporary of Hudson Taylor) who preached that followers of Christ were promised healing for every infirmity, Frost articulates a true biblical teaching and expectation for healing. He has full faith that God can and has miraculously healed even in these modern times--his own family experienced it. But, with full trust in God as our wise, good Lord and Father, he shows how there is no "health prosperity" promise in Scripture. The book simultaneously built my faith in God's power while managing expectations.
I'll be honest; I was reading it to encourage my own faith when I am asked to pray for healing for someone; I've realized I'm pretty fatalistic about health problems. I don't know how much more full of faith I am, but I do think sound biblical teaching on any topic is bound to inform a better prayer life.
