Quoting the Danish Twin Study, Dan Buettner, author of The Blue Zones, stated that “only about 10 percent of how long the average person lives, within certain biological limits, is dictated by our genes. The other 90 percent is dictated by our lifestyle.” Evidently, people have a great ability to affect—positively or negatively—how long they live! But God’s plan isn’t just that we live long lives on this earth. He wants us to live eternally. What does the Bible say concerning our physical health? And is there any connection between physical and spiritual health? The Bible contains the keys to a happy, healthy—and very long—life.
