MUG: Be Killing Sin

“Be killing sin or it will be killing you.” – John Owen

This official RefToons ceramic mug features a bold cartoon illustration of the classic Puritan call to mortify sin.  Inspired by John Owen’s timeless work The Mortification of Sin, the design delivers a daily visual reminder to put the deeds of the flesh to death by the power of the Spirit (Romans 8:13).

Perfect for pastors, seminarians, theology students, Reformed Christians, and anyone who loves church history with a bit of edge.  A thoughtful gift for Reformation Day, seminary graduation, men’s ministry, or just because.

Available in 11 oz or 15 oz.  Dishwasher and microwave safe.  Designed in the signature RefToons style that makes deep doctrine memorable and fun.

Start every morning with a strong reminder to keep fighting. Order your Be Killing Sin mug today!
