Whatever you do, do it heartily, as to the Lord and not to men. COLOSSIANS 3:23
Batwing, raglan, dolman, puffed, set-in, butterfly, paned, hanging, bell —these are styles of sleeves worn throughout history. The expression of someone “having something up his sleeve” refers to an Oriental-style hanging sleeve that was also used as a pocket. Hardworking folks can be spotted by their rolled-up sleeves as they work to accomplish their tasks.
Somehow, the idea of “working hard” as a Christian is lost on many believers, as if spiritual work should never be strenuous. Such a perspective might have drawn a stern correction from a hard worker like the apostle Paul. Not only did he set an example of giving one’s all in service to Christ but he also exhorted his readers to follow his example. We are to work heartily and be “steadfast, immovable, always abounding in the work of the Lord” (1 Corinthians 15:58).
Today, figuratively, if not literally, roll up your sleeves for the Kingdom’s sake!
