On today’s Creation Moments Minute, that amazing fluid inside your body that keeps you alive.
Your heart pumps blood at a speed of more than three feet per second. This means that a red blood cell makes a full trip from your lungs and back in only about a minute. Your red blood cells live only about 4 months. In that time, they have made over 170,000 trips from your lungs to bring oxygen to every part of your body. That means your body must constantly replace them, so your body produces about 2 million new red blood cells every second.
As we learn more about our circulatory systems, we see that physical life is a daily gift from God. Yet, it was the life-blood of our Savior, Jesus Christ, shed on the cross for us in His holy, innocent suffering and death that makes eternal life possible for us.
