Various examples of my preaching and speaking are available online, some even for free.
I preach regularly at St Andrews Baptist Church; all our sermons are recorded and podcast here. I also preach in other places, but I don’t keep a list of what gets podcast and what doesn’t
Recordings of some of my conference speaking are available to buy from Essential Christian here. Highlights include Living Like Maggots: Is preaching still relevant in the C21st? (Baptist Assembly 2009); One People (on God’s place for Israel; Spring Harvest, 2007); and God and Genocide in the Old Testament (Spring Harvest, 2011).
If you look, you can find three Reformation Day lectures I gave at Covenant College in 2009 on iTunes; they are in the Covenant College Chapel podcast.
If you would like to see me in action, two videos of talks I gave at the excellent BMS Catalyst Live event in 2013 and 2014 are available for free here and here. I also spoke on ‘Politics, Power, and Public Leadership‘ at an Evangelical Alliance Council meeting in 2014, and on ‘A Historical Theology of Adoption‘ for Home for Good in 2015.
