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.'
