This book is a mixture of "heretic" doctrines: charismatic, feminist, New Age (meditation) and other pagan ideas. Being provocative and challenging is fine as long as one's case is well aegued. There are no cogent arguments in this book, but it is rather a compilation of bad assertions.
A defintely more serious theology can be found in Gordon Lewis' "Integrative Theology"

Anyone who has ever read Clark Pinnock before will be sorely disappointed in his work "Unbounded Love". Although it is posited to be a theological "BANG!" in favor of Pinnock's "new" love-based theology, it serves as no more than a "blip" on the screen of evangelicalism. It begins with theological presuppositions that can only be characterized as over-simplified fluff with little to no biblical backing. Pinnock's attempt to propose a revolutionary "Good News Theology for the 21st Century"--complete with universalistic ideals, Pelagianistic theology, and ooey-gooey emotional appeal--fails miserably in his marked unwillingness to offend religious groups and social reformers (i.e. feminism, pluralism, black theology, and the like). Basically, the only principle he is willing to stand upright on is that of God's love--and it simply doesn't work that way. Hence, as he desires to say everything to clearly support and define his leftist evangelical case, he comes away having said nothing at all. The only constructive purpose this book can serve a reader is to reveal another giant leap Clark Pinnock made (in 1995) towards heresy in his life-long sprint away from formerly held biblical truth.

In "Unbounded Love" Pinnock & Brow articulate a more complete theology of a loving God than previously attempted by conservative Christians. It is a welcome breath of fresh air to the stale platitudes of the religious right who view God largely as a judge, rather than as a loving father. The authors challenge us to rethink the Bible, sin, hell, salvation, the trinity, prayer, healing, and even the church itself in terms of love. There are plenty of footnotes for those who wish to read further. For those unacquainted with the recent pilgrimage of non-calvinistic thinkers like Pinnock to construct a theology known as "Free-Will Theism," here is one of the best places to begin. Although still considered conservative in its approach, this is moderate theology at its best.
