The 'Christian' publishing scene is awash with poorly written, shallow and quite frankly heterodox opinions and views. Open Theism is front stage at attacking orthodox view of God and this book rightly shows the poor exegesis of the open theistic view. It can be a dense read in places and you may need a good dictionary to help (Kindle is very good here) but this book is needed.
When we seek to worship a corrupted view of God we are not worshipping god at all but an idol of our own making. If you are dabbling in Open Theology - read this book - have your mind renewed.
