The Rev David Watson (1933-1984) the British author and evangelist, once described the church in terms of a bus! The driver was up front and the passengers all faced forward too. Somebody even came and took your money! Like a passenger vehicle, the Christian community moves forward while Jesus steers! Everything that happens inside that "vehicle" is the mission of the church.
The word "mission" in this context is a term that includes all the activities that are performed within a fellowship, church or congregation. In a healthy church, evangelism is one major element, worship another and social activity is another. Together these and other aspects combine into the "Christian mission umbrella." umbrellas date back 3 thousand years even to ancient Egypt. Umbrellas were used not only for protection from the sun but as a symbol of wealth.✞
If one element in this mission umbrella is neglected then the Body of Christ becomes unbalanced. A small ear infection can cause a full grown man to stagger and fall. In the same way, an overemphasis on one element of the Christian mission such as worship to the detriment of others disrupts the Body's delicate balance.✞
