This is a great book. It has impacted me more then I can say and hope I will be more faithful in carrying out the 'great comission'. This is written by an American to an American audience, but it certainly can be applied to British Christians. What he says is stuff we should already know, do, think like, etc as Christians, but so much of the time in the West we don't because we're too comfortable. It is sad that this book ever had to be written, but I am thankful for it. Mr. Platt does not hesitate to 'call a spade a spade'. He is very clear and easy to read. He has no political agenda. He is, most importantly, Biblical. He writes this to see God glorified. Christ emptied Himself for us and called us to take up our CROSS and follow Him.
If you're not sure about buying this book, you can read the first chapter for free online, just Google it. Even the first chapter is helpful by itself.
