“How much more, then, will the blood of Christ, who through the eternal Spirit offered Himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God.” Hebrews 9:14 (NIV)
The human body is an amazing creation, comprised of 11 different systems. Lately, I’ve been thinking a lot about two of them — the cardiovascular system and the respiratory system. These two systems work together to fuel and to cleanse our bodies. Oxygenated blood is pumped by the heart throughout the body, providing oxygen and other nutrients to the body’s tissues. The body uses these elements to produce energy. Simultaneously, the blood carries away waste from the body’s tissues — waste like carbon dioxide and metallic by-products. Deoxygenated blood returns to the lungs, whereby carbon dioxide is removed from the body and blood is reoxygenated.
Amazing , isn’t it!?
When we exercise, our blood and our breath are increasingly important to continue the fueling and the cleansing of our body and its tissues. The body needs more oxygen to meet increased energy demands, which it turn produces more waste to be carried away. The blood and the breath are critical to our life and to our performance.
Funny how the same is true in our spiritual lives as well. Even there, the blood cleanses — that is, of Christ carries away our impurities and sin — while the breath of the Spirit fuels us for good works. (The same Greek word pneuma is used in the Bible to mean both breath and spirit — see May 13, 2014 post, Breathe.)
So the next time you are out on a walk, think about the work of the blood and the breath … and thank God for providing both!
