[tentblogger-vimeo 72840026] Eric Yelsma, founder of Detroit Denim shares his thoughts on calling as it pertains to his work as a blue jean designer. God not only calls people to be pastors and missionaries, but God also calls the assembly-line workers, the stay-at-home moms, the blue jean designers, the construction workers, the graphic designers, and so on. No matter what the work is that you do, God has called you to use your gifts, to do your work, and to serve the people around you.
