Query: Opened my mind, opened my spiritual eyes

I'm writing as a Christian Evangelical, who has had experience in the Charismatic movement. I got this book looking for perspectives on spiritual warfare, which I've neglected until recently. Because Charles Kraft has been at Fuller Theological Seminary since 1969, he writes from a theologically sound, academic, and practical standpoint. In other words, there's no loosey-goosey, name-it-and-claim-it, wish-fulfillment, "Secret" theological trash here. I really appreciated Kraft's solid, non-judgemental explanation of how Christians can be demonized (not "possessed"), and that his ministry is primarily a LOVING one. It was mind opening, and spiritually revealing. I'm reading more of his books - Christianity With Power and I Give You Authority - to learn better how to pray and intercede. I do see the world with different eyes, which seems to come by closing them and praying more.
