Fun Facts:
-Although they are not likely to publicly admit it, many Christian prefer testimonies with a lot of high profile sin at the beginning (i.e. drugs, alcoholism, sex, etc). Because of this, many who became Christians at a young age may feel that they don't have a very interesting testimony.
-Many people in other countries complain that most American Christian testimonies given by those on short term missions trips all sound the same and almost always begin with "I grew up in a Christian home."
