This blog would be a whole lot more fun if we got some discussion going here. There is an idea that I've been toying with that I'd like you to explore with me. We, the church, are the body of Christ. Wouldn't it seem that God, being God with all his intricacies, would take that metaphor much further than just being the hands and feet? For instance, the heart is a muscle that pumps the blood throughout the body. A quick web search brought me to this:

Blood is the liquid pumped by the heart throughout the body. The cells are produced in the bone marrow.

The chief function of blood is to bring oxygen and nutrients to tissues in the body, and to carry away carbon-dioxide, lactic acid and other waste material. It also transports hormones and other substances between organs and body tissues.

Blood is made up of the following main components:

• Plasma - This is the fluid of blood. It is mostly water, with about 4% proteins including albumin, as well as antibodies, hormones and blood clotting factors.
• Red blood cells - These make up most of the blood cells. They contain a red protein pigment called hemoglobin which combines with oxygen so it can be carried around the body. They also contain the proteins which determine blood types.
• White blood cells - These are part of the immune system, and defend the body against infection.
• Platelets - These are sacks of blood clotting chemicals.

Okay, so if you show some interest I'll give you my thoughts on this metaphor later, but I want your thoughts first.
