Close Bio
A native of West Michigan, Michael studied philosophy and theology at Calvin College, received his MDiv from Duke in 2005 and is an ordained Mennonite pastor. Michael and his wife Jodie have two children. Before helping to launch The Colossian Forum in 2011, Michael served for five years as a pastor in Des Moines, Iowa. That experience cultivated a deep desire to aid churches in engaging today’s divisive cultural issues. He is committed to sharing the good news that conflict need not be a threat. Instead, we’re free to receive it as a Christ-given opportunity for discipleship and witness to our fragmented world, a world that can no longer imagine what it means for all things hold together in Christ (Colossians 1:17).
