I’ve attended a number of evangelical non-denominations churches and I found, that the vast majority (95-99%) of those under the age of 40 have almost no Christian theological understanding beyond Jesus died for my sins.  Moreover, even the implications of Jesus dying for my sins is understood only at the most basic levels and, beyond the popular Romans Road, they can’t use the text of Scripture to support the notion.  I specified “Christian” theology earlier because I’ve encountered quite a bit of Buddhist and Hindu theology masquerading as Christianity.  One of the worst is the notion that my material and/or spiritual blessing is tied directly to a quasi-sacramental “quiet time.”  Not that a rigorous devotional life is not important, but this is karma, not Christianity. Moreover, the “Christians” in these churches could not talk at all about what passages of Scripture meant in an objective sense, only how they could apply it to their lives or what it meant to them.  We must recover the strong catechetical tradition of Protestantism and transform youth groups from something that is fun, “relevant”, and meaningless into something that is challenging, biblical, and in my experience young people actual find quite interesting when compared to all the dribble of this world!
