In deciding whether to be a youth group leader, it is key to consider how you would handle a situation where an enthusiastic young Christian was being treated condescendingly by other members of a youth group who generally disagreed with a mainstream Christian teaching.
A great youth group leader will help everyone feel welcomed while looking out for the well-being of enthusiastic young Christians who should be made to feel they are in the right place to freely discuss their support for mainstream Christian teachings.
Christians, in deciding whether to be youth group leaders, a valuable consideration is to think about whether or not you disagree with one or more Christian teachings and if it might irritate you to hear youth group participants talk about those teachings. It is possible you struggle with accepting certain church teachings but you also know you would not become angry with youth group members who brought up those topics. However, you will want to refrain from being a youth group leader if you feel you may end up becoming frustrated by young Christians who fully embrace mainstream Christian teachings.
Also, it is important to want to stand up for young Christians in a youth group who may come under verbal attack by other youth group members who may only weakly support some core teachings. This can be because youth groups may have members who mainly go to be with friends or because of the urging of their parents, for example. What can happen is that the one or two members of a group who enthusiastically embrace their faith may quickly feel like they are not at a Christian youth group at all after realizing no one else shares their support for a handful of mainstream Christian teachings and that even the youth group leaders seem to look on condescendingly.
A necessary trait of a youth group leader is that she or he won't show aggravation at young members who speak in support of mainstream teachings that even they as youth group leaders may have a problem with. Once again, youth group leaders also need to be ready and willing to respectfully stand up for a young Christian who may suddenly find herself or himself at odds with most of the group for supporting a mainstream Christian teaching. A great youth group leader will help everyone feel welcomed while looking out for the well-being of enthusiastic young Christians who should be made to feel they are in the right place to freely discuss their support for mainstream Christian teachings.
