Yet we neither move nor march, but sit in our comfortable pews watching the war from a distance. Christ is the Head, we are His body. As separate individuals we form different parts of this body. Each part of the body has a function. There are no useless parts of the body.
Every part has a function and a purpose.
Now this means that we all have a part to play in the body of Christ - other than pew warmer. It means that if we don't all do our part, the body of Christ will be disabled and handicapped. Not only are we hindering the proper function of the church, we are actually doing positive damage. The church has a lot of useless limbs hanging around. Imagine a football game where one side's team stays on the benches, sending the quarterback into the game alone.
