(I read the 2007 reprint - Roberts may have updated this and changed some things. I hope he did.)
I think this book needs more Jesus. More time spent in the Gospel rather than just its implications and outworkings.
There was also a big stress on how worthy it was for people to give up their jobs and go into the mission field or full time ministry. It is a wonderful thing, but not for everyone. We need Christians in allsorts of different contexts and workplaces, but Roberts seemed to imply that a Christian ministry calling was of more value, or showed more willingness to sacrifice and live for Jesus. He could have spent time reflecting on how we can all be distinctive for Jesus in every different context and situation we're in.
I think this book may leave lots of people feeling guilty and that they don't really love Jesus enough. So again, we needed more time spent seeing Jesus and being pointed to Him in our weakness. The book ends with the question, are you giving up enough for Jesus? I wanted the book to end with Jesus, for us to lift our eyes to Him, to see how He lived distinctively for His glory and our good, how He lived the life we ought and never could, how He died in our place for all our sin and worldliness, and how by His death and resurrection He brings us into a life we could never deserve or earn. And it is Him who gets the glory!!
Here are a few quotes I did enjoy:
'A soldier in the First World War was badly wounded in the trenches. As he lay in hospital a doctor had to give him some bad news. 'I'm sorry - you've lost your arm.' The soldier replied, 'I didn't lose it. I gave it.' In a similar way, Jesus did not simply lose His life - He gave it. There could be no greater gift. And it had a purpose - to 'redeem' us. Without Christ, our situation was helpless, but He has set up free.' p.9
'And if you are single and tempted to feel sorry for yourself for being 'left on the shelf', remember that God does not have a shelf. Paul wrote to the Christians at Corinth: 'I promised you to one husband, to Christ, so that I might present you as a pure virgin to him' (2 Cor. 11:2). If we are Christians, we can be confident that Christ has chosen us as 'his bride' and we will remain married to him for ever.' p.66
