People leave because other things in life become more important that their faith . They slowly drift away preoccupied by business, pleasure, material ambitions, personal problems or other hard realities that are part of life. There are so many temptations around that can lead young people away from the faith. Leaders need to provide spiritual safe havens where youth can find refuge from the attraction of the world but also a context in which they are strengthened to deal with the distractions of life. Also leaders need to teach youth about God and the realities of the spiritual world around them.
People leave because they never personally owned their own faith .
They have made few, if any, authentic faith choices in their lives, having conformed to the spiritual expectations of others. Most young people feel that they are expected to behave and believe in a certain way. They never feel free to make decisions about what or how they will believe. To encourage a first-hand faith leaders need to aim for authenticity, decide to let go, encourage freedom with responsibility and make room for failure. Repent and do the things you did at first.
