Paul Jarzembowski talks about the important differences between young adult and youth ministry:
Young Adult Ministry is not Youth Ministry. Because of the proximity of ages between adolescents (those in their teenage years) and young adults (those in their late teens, 20s, and 30s), youth and young adult ministry are sometimes confused or fused together. They have some similarities — both groups experience times of transition and are proficient in technology, but they are radically different populations with different needs and ministry with and for them should be distinct and separate, yet still collaborative in the pathway from one to the next.
