I am not reformed nor am I a Calvinist, but I do give this book 5 stars simply because it is one of the clearest written works on the subject of soteriology from a reformed protestant perspective. Hoekema is very precise, fluid, and clear. You would be hard-pressed to find a better summary on Reformed Soteriology than this book. Though, I disagree with him fundamentally on many things, I cannot give him a bad rating because of that. He clearly states in the beginning that his book is a guide to Reformed Soteriology- and that it is. If you are Reformed or Calvinist you will greatly benefit from this work. If you are of a different tradition, a new Christian, or maybe a non-religious person wanting to just understand this subject, then you will certainly be educated on this unique Christian theological tradition. It's somewhere between High School level and College, so don't let its size intimidate you.
