God reveals Himself to humanity in two "books" - the Bible and Creation. We're used to using the Bible to explain the gospel, but is it possible to use the natural world to draw people to Christ? Andy Bannister and Simon Wenham explore this possibility with American biologist Xandra Grieme.

Xandra's book is Forty Answers From Nature: What We Can Learn about God, Life, and Ourselves by Studying the Natural World and her website is Biopologetics.com

Xandra Grieme is a speaker and author. Her scientific research began with studies in parasite behavior. She later worked in a human blood lab developing treatments for blood cancer until finally moving on to conservation of songbirds in New Zealand. Xandra also studied theology at OCCA The Oxford Centre for Christian Apologetics, which inspired her to begin writing on the philosophy of science. Xandra has spent extended time living and researching abroad in Asia, Africa, Oceania, and the UK. She is passionate about educating Christians on our role as stewards of God’s natural world. Xandra currently lives in Colorado where hikes through the Rocky Mountains are a constant reminder of God’s power and goodness.

What does it really mean to live out your faith in the marketplace? In this episode of PEP Talk, Simon and Gavin sit down with Gideon Okoli for a powerful conversation about purpose, leadership, and influence beyond the church walls. Drawing inspiration from Biblical figures like Joseph, Esther, and Daniel, Gideon challenges the idea that spiritual impact only happens in a 'ministry setting' — arguing instead that God positions people strategically in business, government, and everyday work. If you’ve ever wondered how your faith and vocation connect, this episode will inspire you to rethink where and how you can share your faith.

Your church might have the best outreach programmes and top-notch facilities, or maybe its struggling to survive on a dying high street in a small market town. Either way, God surprises us with unexpected seekers, especially during this 'odd cultural moment', coming on unconventional journeys to faith. How can we be ready to participate in what God is doing, wherever He's placed us? Simon and Gavin speak with "Two Pastors in a Pub" podcaster Tom Wharin, this time on PEP Talk.

Tom Wharin is the minister of Chipping Sodbury Baptist Church in South Gloucestershire. He participates in various Baptists Together ministerial recognition (recruitment and training) groups and is passionate about mentoring and discipleship (of ministers and of Christians in general). He goes mountain biking whenever the opportunity arises and is one of the pastors in the Two Pastors in a Pub podcast, with Matt Frost and Karen Simson. He is married to Jo and they have four young adult footballing kids.
