They support your entire body all at once, they always have time for you, they don't talk back. But they really come into their own when when you are so exhausted you can't sleep, when you are beyond tired and into a zombie-like comatose, when you are so tired that your eyelids, the tiniest of tiny slithers of skin, become too heavy to hold up. It's when you get to that stage that you are able to do the end of day flop unto the deep soft duvet, surrender to your body and slip serenely into deep, deserved, delicious sleep.
But then sometimes it's just nice to lie-on. You've had your nights sleep, you have recovered but now it's just preferable to stay where you are. It's warm and cosy where you are and it's cold and busy where you're going. But hey, you weren't made to lie in bed, you were designed to do stuff, useful stuff so get up and get on.
Of course there are more comfort traps than double beds - there are jobs, relationships, churches, dole offices and many more things that we can lounge about in longer than necessary. They can be really useful, supportive, encouraging and productive but they can become so comfortable or safe that we wallow in them longer than we should. Challenge yourself to get up, shake yourself down and get on with life.
Lazy hands make a man poor, but diligent hands bring wealth.
