At times we become aggravated and this is when our true Christianity shows face.  As a Christian we have to be Christian all the time not just when we feel like it.   Being a Christian is a way of life, not just a feeling.   Some examples:  Do we treat our co-workers with respect? Do we curse at work and act differently than we do at home?  Is church the only time and place we act like a Christian?  Think about this and really strive daily to be an example to others.  God will reward you in your efforts to promote Christianity.
