As Jacob continues toward Canaan in obedience to God’s call, he comes up against another significant obstacle: Esau is coming to meet him Genesis 32:1–12 — preparing for conflict with a small army. Jacob’s reliance upon God’s covenant promises, and his humble prayer, are models for today’s Christians. We may pray with confidence as did Jacob, for the reality of those promises are even greater for us through Jesus Christ.

Q. 14. What is sin?
A. Sin is any want of conformity unto, or transgression of, the law of God.

In this episode, we sit down with Dr. A. Craig Troxel, Robert G. den Dulk Professor of Practical Theology at Westminster Seminary California. Dr. Troxel delves into his thought-provoking chapter on the communion of the saints from Theology for Ministry, a festschrift for Dr. Sinclair Ferguson.

What does it mean to build a spiritual community within the church? How can pastors cultivate a culture of love, service, and mutual respect, reflecting the Spirit-endowed riches of Christ’s gifts and graces? Dr. Troxel explores these profound questions, emphasizing the “one another” commands, the forms of mutual service, and the essential role of love in the life of the church.

Dr. Troxel also sheds light on the transformative power of worship and the vital role of the Spirit of God in animating the hearts of God’s people. He concludes with a compelling vision of the communion of the saints as more than just a gathering of individuals—it’s a sacred communion of those set apart for divine privileges and consecrated purposes.

Whether you’re a pastor, theologian, or simply someone seeking to deepen your understanding of community within the Christian faith, this episode offers rich insights and practical wisdom. Join us for a conversation that touches the very heart of what it means to be part of the body of Christ. 

Dr. Troxel is the author of With All Your Heart: Orienting Your Mind, Desires, and Will Toward Christ (Crossway). His research interests include pastoral theology, Reformed spirituality, the doctrine of the church, and biblical teaching on the heart.

Q. 13. Did our first parents continue in the estate wherein they were created?
A. Our first parents, being left to the freedom of their own will, fell from the estate wherein they were created, by sinning against God.

Danny Olinger and Camden Bucey discuss the sixth chapter of Machen’s classic book, Christianity and Liberalism. In this chapter, J. Gresham Machen explores the differences between the liberal and Christian views of salvation. He argues that liberalism finds salvation in man, while Christianity finds it in an act of God. Machen critiques the moral influence theory of the atonement, which denies the substitutionary character of Christ’s death and the wrath of God. In contrast, he emphasizes the need for a propitiation for sin and the centrality of the cross of Christ in the Christian view of salvation.

Machen concludes that the doctrine of salvation is essential to the Christian faith and that liberalism and Christianity are fundamentally incompatible on this question. The chapter provides a clear and detailed analysis of the theological and biblical foundations of the Christian view of salvation, and highlights the importance of this doctrine for the Christian life.

Q. 12. What special act of providence did God exercise toward man in the estate wherein he was created?

We welcome Chris Castaldo to the program to explore the Beatitudes. In his book, The Upside-Down Kingdom, Castaldo offers a fresh perspective on these familiar teachings of Jesus, showing how they reveal God’s heart for the poor, the meek, and the persecuted. He also provides practical guidance for how we can live out these values in our daily lives, both as individuals and as a community of believers. The book is recommended for anyone seeking to deepen their understanding of the gospel and its implications for our lives today.

Castaldo argues that the Beatitudes challenge our cultural assumptions about power, success, and happiness, and call us to embrace a different way of living that is grounded in humility, compassion, and justice. Castaldo also draws on his own experiences as a pastor and theologian to provide practical guidance for how we can live out these values in our daily lives. Overall, The Upside Down Kingdom offers a fresh perspective on the Beatitudes that is both challenging and inspiring.

Chris Castaldo (PhD, London School of Theology) is the lead pastor at New Covenant Church in Naperville, Illinois. Follow him on Twitter at @chriscastaldo.
