For the most part I am drawn to the mystical understanding of God. What I mean by that is that God cannot be explain away/proven by the rational people. To often in certain Christian circles they feel if certain things can be known without a doubt more people would have faith in Jesus. This is a very modern view on how people know (ie epistemology). The other matter is that I believe in Grace and do not understand how the sinner's prayer became the way a conversion begins(or maybe that too often the sinner's prayer is seen as the end of a conversion and not the beginning).
The book in essence is about faith and what does it mean when the Bible talks of faith. I think one of the problem is that the Bible talks about faith in a drastically different manner than it is expressed in the Western world. Or faith is used so commonly by people that its meaning has been eroded to the degree that faith in a Christian context needs to be re-understood as much in post-modern context.
I am drawn to Capon's interpreting of the parables that make Grace all about what God has been doing from the creation of the world through Jesus. Too often the parables are turned into what people need to be doing to gain God's favor. The problem is if one believes Sin is a problem then their is nothing we can do, but have faith(trust) in Jesus. This faith does not alter what Jesus did with the sins of the world. It does alter how we live in the world. Do we believe that their is no reason to have guilt, do we forgive others, do we seek punishment for wrongs done to use. The list could go on and on.
Faith is important is that even if scholars could prove that Jesus was resurrected from the dead beyond a shadow of a doubt it still requires an act of faith.
