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 [https://www.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.

Marketplace Apostles (with Gideon Okoli)

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 [https://www.cs-bc.org.uk/two-pastors-in-a-pub] podcast, with Matt Frost [https://www.solas-cpc.org/pep-talk-with-matt-frost/] and Karen Simson.  He is married to Jo and they have four young adult footballing kids.   

Unexpected Seekers (with Tom Wharin)

What is it that holds you back from sharing the Gospel? For most of us, it boils down to a lack of confidence. We don't have confidence in our knowledge to field difficult questions, we don't have confidence that we won't get 'cancelled' and we might even lack confidence in our own faith itself. So you're not alone! That's why Solas runs 'Confident Christianity' training across the UK to help churches regain their confidence in evangelism. Gavin Matthews and Steve Osmond explain how it works and who it helps.

To find out how Confident Christianity can help your church, visit the Solas website here [https://www.solas-cpc.org/conference-partnerships/].

Steve Osmond is a full-time speaker and writer for Solas, focussing primarily on Scotland. He is enthusiastic about evangelism and regularly speaks at universities around the country on the big questions of life and the truth of Christianity from a range of perspectives. He also spends much of his time working with churches and other Christian groups, both to grow their faith and equip them to share their faith in Jesus persuasively.

Addressing a Crisis of Confidence

Here in the UK, we might encounter Jewish people that range from secular atheists to highly religious. But Christians can be reluctant to engage in gospel conversation for fear of political pitfalls or cultural offence. How can we navigate the issues we might encounter when sharing the message of Jesus with his original ethnic group? In this episode of PEP Talk, we find some great encouragement and wisdom around evangelism to Jewish people.

Research indicates that many people will first consider whether Christianity is something good, before they consider whether or not it is true. But for both these questions, the discipline of philosophy informs how we think about them. Can a stuffy old academic discipline really help much with modern spiritual questions? Steve Osmond and Simon Wenham learn more about what philosophy and apologetics brings to evangelism.

The Good, The True, The Beautiful: Apologetics for Evangelism (with Peter S Williams)

In the first few weeks every year, Christian Unions across the country put in a concerted effort to reach their campuses - with around 85 'events weeks' happening recently.  For many young people, their time at university is a formative and energetic experience, and it is a great opportunity for students to reach their friends for Christ. UCCF is helping them do this through 3"D" ministry: Delighting in Jesus more deeply, Displaying Him more fully and Declaring Him more boldy. UCCF leader Matt Lillicrap explains more to Gavin and Simon on this week's PEP Talk.

Matt Lillicrap studied Medicine in Newcastle and qualified in 2006. Until 2013 he worked as a junior doctor, alongside a stint as a staff worker for Christian Medical Fellowship.

Have you ever wondered why music moves us? It transcends culture, yet is an important part of most cultures. Today on PEP Talk, we reflect on how the gift of music speaks to us about God's character. That makes it an excellent medium for communicating God's truth not only within the church, but also with the culture around us.

Many sporting clubs are the largest social group in any given local community. Do the local churches view them as rivals, or mission fields? Today, more clubs are recognising the competitive benefits of caring emotionally and spiritually for their athletes, opening up huge opportunities for Christian ministry. Here on PEP Talk, sport enthusiasts Gavin Matthews and Simon Wenham learn more about the the area of sports chaplaincy.
