A highly challenging call to respond with our whole hearts to Christ. To follow our Saviour is not about being nice. It's about taking risks. Simon writes: 'There's a battle going on for our hearts. What I watch, what I listen to, what I spend my time and money on - all these erode my true sense of identify and worth as a child of God. Where is the vigilance, the discernment, the scrutiny? Our hearts are far too precious to treat with such lax indifference ...I want to play my part in turning the world upside down; I want to be fearless, bold, uncompromising and passionate in reaching out to the lost on behalf of the King of Kings; I never want to get over the grace of God.'
