People regard discussions focused on faith in a variety of different ways. Some people see talking to others about their beliefs as a key component of evangelizing and do so every time they get the chance. Other people find religion to be deeply personal and are not comfortable bearing their soul so completely to other people. As such, people vary wildly on how willing they are to discuss matters of faith with other people. Christians, however, should never be ashamed to identify themselves as such even if they are uncomfortable having a deeply personal or theological discussion about religion. 

If you used to be happy to talk someone’s ear off about Jesus and now you refuse to so much as mention your faith in casual conversation, there is a problem. A recent bad experience may have made you reluctant to share like you used to, but you have to work to move past that. Otherwise, you may find yourself feeling embarrassed to be a Christian. At that point, your faith has already begun slipping rapidly through your fingers.
