Kevin Cauley writes on Preacher’s Files:
When we think about the word “missions” what naturally comes to our mind are specific works (primarily in other countries) in which the church participates by either contributing funds or sending individuals to be involved. The Latin root behind the English word “mission” simply meant “to send.” In the secular sense, the word has the idea of a specific task charged to an individual or group. In the religious sense the word entails a work of the church intended to propagate spiritual growth either spiritually or numerically. As I mentioned, we usually think of missions as being outside of the local congregation in some foreign country, or at least, away from our doorstep. However, there is a great mission to be done at home as well and we need to not only be mission minded locally as well as remotely.
