In his book Fearfully and Wonderfully Made, co-authored with Philip Yancey, Dr. Paul Brand observed, “A hummingbird heart weighs a fraction of an ounce and beats eight hundred times a minute; a blue whale’s heart weighs half a ton, beats only ten times per minute, and can be heard two miles away. In contrast to either, the human heart seems dully functional, yet it does its job, beating 100,000 times a day [65–70 times a minute] with no time off for rest, to get most of us through seventy years or more.”
The amazing heart so thoroughly powers us through life that it has become a metaphor for our overall inner well-being. Yet, both our literal and metaphorical hearts are prone to failure. What can we do?
The psalmist Asaph, a worship leader of Israel, acknowledged in Psalm 73 that true strength comes from somewhere—Someone—else. He wrote, “My flesh and my heart may fail, but God is thestrengthof my heart and my portion forever” (v. 26). Asaph was right. The living God is our ultimate and eternal strength. As the Maker of heaven and earth, He knows no such limitations to His perfect power.
In our times of difficulty and challenge, may we discover what Asaph learned through his own struggles: the Lord is the true strength of our hearts. We can rest in that strength every day.
