Although churches do many, many things in many different ways, they have but FIVE basic tasks. Worship, or our 'God-relationship' is the keystone of all we do as Christians and as a part of the church. We seek to be inclusive, and not exclusive. There must be a balance of all the tasks, and often evangelism is valued as the task of the church, and fellowship is seen as an option. But just as a person cannot do carpentry, or teach school, or compose symphonies when he or she is too ill to function, even so the Body of Christ cannot evangelize or serve or educate when it is out of sorts within itself.
Fellowship is much, much more than parties and social times.
It is God's love being expressed within the church.
