Summary of Chapter 17
The 17th 'lie' covered in the book is that 'the cross was God's idea'. Young says there is nothing good about the cross. If it was God's idea... that would reflect poorly on God (God would be a cosmic child abuser). Rather, the cross (a torture device) was our idea. God knew from the beginning that we would do this. God submitted to it and transformed the cross into a symbol of grace.
Though this chapter would surely offend some people (Divine Determinists/Calvinists), I think Young is correct. God's plan was not to have Jesus tortured on a Roman cross. That's what we did. But God lovingly works through tragedy to accomplish good. No objections here.
