Our heart beats about 100,000 times every day, pumping blood to every cell in our bodies. This adds up to about 35 million beats a year and 2.5 billion beats in an average lifetime. Medical science tells us that every contraction is similar to the effort it would take for us to hold a tennis ball in our palm and give it a good hard squeeze.

Yet as amazing as our heart is, it is only one example of a natural world that is designed to tell us something about our Creator. This is the idea behind the story of a man named Job.

Broken by a series of mounting troubles, Job felt abandoned. When God finally spoke, He didn’t tell Job why he was suffering. Nor did the Creator tell him that someday He would suffer for Job. Instead, He drew Job’s attention to a series of natural wonders that are always whispering to us—and sometimes shouting—about a wisdom and power far greater than our own (Job 38:1-11).

So what can we learn from the complexity of this hardworking muscle, the heart? The message may be similar to the sound of waves coming to shore and stars quietly shining in the night sky. The power and wisdom of our Creator give us reason to trust Him.
