“Be killing sin, or it will be killing you.”
This Reformed Christian long sleeve tee from Calvinist Apparel carries John Owen’s classic charge to mortify sin, framed by an upright sword piercing a skull and an open book of Scripture, intertwined with green vines and red roses, set against black.
A Puritan’s charge
John Owen, the great Puritan theologian, wrote that believers must be killing sin, or it will be killing them. Drawing from Romans 8, which calls believers to put the deeds of the body to death by the Spirit, Owen’s work on mortifying sin remains one of the most searching accounts of the Christian’s ongoing fight against indwelling sin. This design puts that charge on your chest: dramatic, historic, and impossible to miss.
The design
- Sword, skull, and open book: A central composition of an upright sword piercing a skull and an open book of Scripture, the means by which sin is put to death.
- Vines and roses: Green vines and vibrant red roses intertwined through the piece, life breaking through even where the theme is death to sin.
- Distressed white typography: “Mortify Sin” across the top, with Owen’s maxim, “Be killing sin, or sin will be killing you,” along the circular border.
- Black background: A high-contrast palette that gives the whole design its weight.
A charge with history
The phrase “mortify sin” comes from Romans 8, and John Owen (1616–1683) built an entire treatise around it, On the Mortification of Sin in Believers. His maxim, quoted on this design, has become one of the most repeated lines in Reformed and Puritan circles.
