Things just
aren’t made to last. How many people do you know that keep their cars 10 years
or longer? Maybe a few, but not many. Some people purchase a new automobile
every year or two, others hang onto them for several years. But we know that
cars have a limited lifespan. Trade it in before it breaks!
The same applies
to clothing, appliances, eyeglasses, even paint. Most smartphones have an
expected life of two years. By the time our mobile provider contract is up,
there’s a totally new version available that makes our old cell phone seem like
it has a rotary dial. And computers? We might try to squeeze every day out of
them that we can, but with the advances in technology, your computer is
obsolete almost before you can get it home and plug it in.
We purchase
things fully knowing that almost before we realize it, it’s time to replace
them. “Planned obsolescence” is one term for it. Products are manufactured with
enough durability that they don’t break or deteriorate within the first few
months or years, but sooner or later they become old and worn, in need of
replacement. Or the new version is so advanced we feel foolish clinging to the
old one.
This model of the human heart, on Discovery Fit & Health's website, shows an amazingly durable organ. |
So I always
marvel about the endurance and longevity of the human heart. We occasionally
hear of people having heart transplants, but for most of us the heart we’re
born with is the one we’ll take to the grave. That’s why coronary health is of
increasing importance. People are living longer and if they don’t take
precautions, heart disease looms in their future. If you have a heart attack
you can’t simply go to a used heart store and get a new one.
A normal heart at
rest can beat from 60 to 100 times per minute. The average person, according to
the Mayo Clinic, has a resting heart rate of 72 beats per minute. That
translates to 4,320 beats in one hour; 103,680 beats in a 24-hour day; 38
million beats in a single year. And that doesn’t include faster heart rates
during times of exertion and stress. Applying those statistics to a 70-year
human life span – and many people are living much longer than that – a single
heart will beat non-stop more than 2.7 billion times. That is a lot of lub-dub,
lub-dub, lub-dub!
In a day or so
I’ll mark seven years since undergoing open-heart surgery. It involved four
arterial bypasses and, for good measure, an entirely rebuilt ascending aorta.
(The old one was on the verge of popping, which isn’t a good thing.) So when
Christmas rolls around, I regard the past year as another gift. Other than the
half-hour or so when my heart was stopped during surgery, with a heart-lung
machine filling the gap, my heart has been beating and pumping without fail.
Over the succeeding years I’ve engaged in a consistent cardio exercise program (my resting heart
rate is 60), I’ve tried to eat better (there’s still room for improvement), and
I’ve taken my medications as prescribed. This marvelous blood-pumping machine
God gave me more than six decades ago has served me well.
Most physicians
and scientists would tell you the heart is nothing more than tissue and muscle,
designed extremely well for performing a very specific task. The Bible,
however, views the heart differently. It describes the heart as the seat of
emotion – and motivation.
For instance, one
translation of Proverbs 4:23 states, “Keep your heart with all
vigilance (guard your heart), for from it flow the springs of life.” As the prophet Samuel searched for a new king for the people of
Israel, God told him, “The Lord does not
look at the things man looks at. Man looks at the outward appearance, but the
Lord looks at the heart” (1 Samuel 16:7). And Jeremiah 17:9 declares, “The heart is deceitful above all things and
beyond cure. Who can understand it?”
Obviously these passages aren’t
referring to physical properties and functions of the human heart, but do suggest
there may be a spiritual dimension to the marvelous muscle. For years following
my surgery, I volunteered at the hospital, visiting patients who also had
undergone open-heart procedures. It was not unusual for even strong,
tough-looking men to have eyes fill with tears as they reflected on what they had
just experienced – the fact they had ventured to death’s door and then stepped
away.
So as I take time to reflect again on
the blessing I have in a refurbished physical heart, I’m also reminded of
Jesus’ admonition about the spiritual heart: “For where your treasure is, there your heart will be also.” Perhaps
He had in mind the warning from Proverbs 21:2, “All a man’s ways seem right to him; but the Lord weighs the heart.”
Where is your heart today?
