Human knowledge is limited

I've had these articles bookmarked to share for quite a while.

The first, "Why Exercise Won't Make You Thin" is an article about exercise and weight loss. A quote from the article:

"In general, for weight loss, exercise is pretty useless," says Eric Ravussin, chair in diabetes and metabolism at Louisiana State University and a prominent exercise researcher. Many recent studies have found that exercise isn't as important in helping people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser — or, for that matter, from magazines like this one.

The second is "Inadequate vitamin D levels common in US children". A quote from the article:

Parents can help their children get enough vitamin D by making sure they spend at least 15 to 20 minutes in the sun without sunscreen [emphasis mine].

I share these articles, because we often hear the professionals making bold declarations about what we should or should not do. But human knowledge is always growing and changing. Good advice last year might not be good advice this year. I value the opinions of doctors and scientists and I understand that these articles are not telling us to quit using sunscreen and exercising. But they are a reminder that true wisdom comes from God and human knowledge is limited.

Do you not know?
Have you not heard?
The LORD is the everlasting God,
the Creator of the ends of the earth.
He will not grow tired or weary,
and his understanding no one can fathom. Isaiah 40:28
