Nominal Christians are like marathon runners who signed up for the race, got their official number, and bought the fancy running gear—but never went out and did the actual training ahead of time. They can’t run the race because they have not prepared. They haven’t developed the habits of faith—like prayer, Bible study, and worship—that would transform them into true disciples. They are not part of a community that can sustain and inform their worldview. They have the T-shirt but not the ability to complete the race. So they run in vain.
