Be Killing Sin Tee
John Owen said it in 1656. It hasn't stopped being true.
"Be killing sin or it will be killing you." Seven words that have convicted more men than most sermons. This shirt puts that conviction on your back and lets it do the work.
For the man who takes sanctification seriously. The one who knows the difference between behavior modification and actual mortification. The guy whose bookshelf has more Puritan paperbacks than anyone in his small group.
Comfort Colors 1717 garment-dyed tee. Soft heavyweight feel from the first wear. Quiet enough to wear anywhere, loaded enough that the right person stops and reads it twice.
- Garment-dyed Comfort Colors 1717
- Soft heavyweight relaxed fit
- Back graphic print
- Runs true to size, size up for an oversized fit
For the Reformed believer. The serious Christian. The one who actually read Mortification of Sin and underlined half of it.
