Almost all practicing Christians believe that part of their faith means being a witness about Jesus (ranging from 95% to 97% among all generational groups), and that the best thing that could ever happen to someone is for them to know Jesus (94% to 97%). Millennials in particular feel equipped to share their faith with others. For instance, almost three-quarters say they know how to respond when someone raises questions about faith (73%), and that they are gifted at sharing their faith with other people (73%). This is higher than any other generational group: Gen X (66%), Boomers (59%) and Elders (56%).
Despite this, many Millennials are unsure about the actual practice of evangelism. Almost half of Millennials (47%) agree at least somewhat that it is wrong to share one’s personal beliefs with someone of a different faith in hopes that they will one day share the same faith. This is compared to a little over one-quarter of Gen X (27%), and one in five Boomers (19%) and Elders (20%). (Though Gen Z teens were not included in this study, their thoroughly post-Christian posture will likely amplify this stance toward evangelism.)
