Addressing the spiritual development of young people has the potential to strengthen youth work and its outcomes. Spiritual development matters because it is an intrinsic part of being human and because young people themselves view it as important. This article reviews the research that points to positive impacts of spiritual development for youth and notes that in an increasingly pluralistic society, everyone needs to build skills for negotiating religious and spiritual diversity. The authors propose that spiritual development involves, in part, the dynamic interplay of three dimensions: belonging and connecting, awareness and awakening, and a way of living. Three initial challenges and opportunities are emerging: empowering youth to explore core developmental issues, motivation and focus, and multisector engagement. (Contains 1 figure and 35 notes.)
