Growing up, I wasn’t much into video games. But I can remember one early game that could keep me fascinated for hours. It was an early version of “Sim City,” a game where you got to build a new community from the ground up: putting in roads, housing, industrial space, government offices, and parkland. It was up to you—the creator of this new world—to determine how money would be raised, how the quality of life for the citizens could be improved, and how land was to be used. As Jesus begins to build his kingdom in Mark 3, he chooses its first citizens: twelve disciples who will eventually become his ambassadors to Israel and his witnesses around the world. What does it mean to be a citizen of this new kingdom, a citizen of the new creation that is already dawning in our midst?
