Most people would be horrified to learn that the surface of their body is as densely populated by hundreds of thousands of little animals as a tropical rainforest. By far the most common is the mite which feeds off the dead skin that flakes off your body (about 10,000 flakes a day) and which is the major componenent of the dust in your home.
"Well done, good servant; because you were faithful in a very little, have authority over [more]..." (Luke 19:17, NKJV).
But don't think you can wash them away - you can't! Take a warm shower or bath and they will simply multiply. They love that too! In actual fact, you don't want to get rid of them because they are doing you an invaluable service - they are also eating and destroying harmful bugs that land on you.
There's an even more remarkable mite that lives on the skin of your hair called the Follicle Mite. Right now there are probably around 120,000 of them there. They live in the follice holes where your hair grows and gorge themselves on delicious bacteria and keep your head clean. When they're thirsty, they sip on our hair oils. Again, don't panic. Those who are born without this zoo on their head usually end up with bacterial infections because our skin can't fight them alone.
These mites live in a symbiotic or mutually advantageous relationship with us. They're our friends and we should be grateful for them. The fact that we can't see them doesn't mean they're unimportant.
Which ought to make us pause and appreciate that the little things in life are often just as important - if not more important - than the big ones. It is a mistake to think that everything that's important has to be 'big' or 'important' or 'famous'. Little people are important too. A little bit of kindness goes a long way. A little 'thank you' or a little smile can brighten someone's day. You see, Yahweh loves the little things we do because we, who are also little, belong to Him and He cares for us.
Be faithful in the little things and the big things will follow.
