John Wesley on 1 Corinthians 9:25

And every one that there contendeth is temperate in all things - To an almost incredible degree; using the most rigorous self denial in food, sleep, and every other sensual indulgence. A corruptible crown - A garland of leaves, which must soon wither. The moderns only have discovered that it is "legal" to do all this and more for an eternal crown than they did for a corruptible!
