Psalm 139

in one definition in the dictionary it says:

anything that is constantly changing as in color and pattern.

You are unique and most definitely constantly changing.

Psalm 139:13-14

For you created my inmost being;

you knit me together in my mothers

womb.

I praise you for I am fearfully and

wonderfully made;

your works are wonderful, I know that full well.

We are knit together in our mothers womb and there is a specific pattern or design for each of his kaleidoscopes. Without light a kaleidoscope wouldn't be much fun. You are not a functioning "beautiful form" if your life has grown too busy, or if you've just become relaxed in your walk with Christ.
We can only see our true beauty, our beautiful changing pattern, when light is reflected through us. If our focus is wrapped in our own failures, we can't see Christ as our source of light.

His radiance shines through us!

Kaleidoscopes are beautiful when held up to the light, they are also especially fascinating when they are twisted and turned by the spectator. When the colors and patterns change and take new shapes you can truly see the beauty and wonderfulness of the kaleidoscope. God is the primary spectator of our lives. Sometimes he twists and turns us in ways that may seem to make us blurry and fuzzy for a while, but if we let him fine-tune us, our lives will come brilliantly back into focus!
