Amy McEntee and Nora Bradbury Haehl give advise about using issues currently facing young adults as a basis for ministry:
Consider what issues the young adults in your area are facing. They may be leaving for college, graduating from college and looking for jobs, trying to figure out their finances, wondering how to cook something other than noodles, getting married, getting divorced, or caring for children or aging parents. Brainstorm a list of issues you have observed or know are typical for young adults. Some issues will be specific to an age group or subset, while others will be universal — go ahead and identify them as such.
