John Van Sloten is a Calgary pastor who enjoys finding his faith is the most unlikely of places. He's written about it a variety of books about science, worklife and even Metallica. In a recent sermon for his Marda Loop Church, Van Sloten spoke about Lego, inspired by watching his grand-daughter play with the ubiquitous building bricks and having her own "Eureka" moment. John Van Sloten spoke with Russell Bowers to expand on what he found when he issued his own Theology of Lego Challenge."
