I came across this in my Bible reading this morning. Proverbs 18:9 A lazy person is as bad as someone who destroys things.
It reminded me of a lesson I learned years ago. A wise man named Tom Rees taught me that there is always a fine line between what we need and what will destroy us. In this case, there is a fine line between rest and laziness. There is a lot of talk out there about "taking care of yourself first". It sounds good and makes sense, but again, when pushed too far it gets dangerous.
I'm all for resting and taking steps to see that we are healthy people. But how quickly we can cross the line from taking care of ourselves to just plain old selfishness. The fact of the matter is that Jesus taught us this in Matthew 6:33 "Seek the Kingdom of God above all else, and live righteously, and he will give you everything you need."
Rest. Be healthy. But above those and all else, seek God out. He is the source of all we're looking for.
