In Mark 7:1-23, we find Jesus arguing with opponents over how to interpret Scripture. Zack finds three phenomena here and argues that all of them are important for us.

Jesus' walking on the water reveals that He is God. Zack reflects on why this fact -- and the sort of God that He is -- makes all the difference for us.

The most dangerous thing a pastor does; spiders held over a fire; a child's drawing of the Hong Kong skyline: Zack marvels at what God's calling us to participate in His ways tells us about God's love for us.

White plastic fans; overwhelming trees; every meal a miracle: Zack reads the feeding of the 5,000 in Mark 6 as an instance of the crowd not knowing that a miracle is occurring -- much like us in every meal we enjoy. For a handout, visit covmin.org/sermons

Katharine Drexel, Isabelle of France, tetrarch Herod: Zack considers why this story of John the Baptist being beheaded is included in the gospel and concludes that we learn something important about when to listen and when not to listen.

Walking around Canadian towns and asking strangers to stay with them; donkey carts tipping over; singing U2 songs in public with college students: In this third of three sermons on Mark 6:6b-13, Zack talks about why we evangelize and, based on Mark 6:6-13, what faithful evangelism might look like.

The heart of early Christian faith; entertaining angels unaware; a man sewn up with a shoelace: In this second of three sermons on the sending of the Twelve in Mark 6:6b-13, Zack discusses the centrality of hospitality to our faith and why, exactly, hospitality is so important.

Riding along for errands; church diapers; quitting a lucrative job: In this second on three sermons on Mark 6:6-13, Zack plumbs Scripture and experience to explain why Christian teamwork is so important. For a handout, please visit covmin.org/sermons.

Blinded by sparrow droppings and mustard plasters; praying for a dead father; Perpetua and her brother: Zack talks about God’s delight in our praying for the impossible. For a handout, visit covmin.org/sermons
