This isn't at all how God intended for we, His beloved daughters, to be.
...Do you remember, way back in Genesis, when Adam was lonely? God, in His loving kindness, provided Eve to be the perfect partner Adam was in need of. With great awe and wonder, the Man exclaimed,
"This [is] now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man."
..Or, in other words: :)
"Oh. My. Goodness. She's...gorgeous! I can't believe it..."
What do you think Eve looked like? She may have been very beautiful. In fact, I am certain she was very beautiful, because she was God's perfect creation. But, she may have not been considered "gorgeous" by today's standards. Who knows? Nevertheless, Adam thought she was wonderful, and so did her Maker. And if God thinks something is "very good," then you better believe it is! ;)
What does that say about us? Well, we, too, are made in the image of God. Of course, sin entering the world has made it possible for us to become unhealthy and sick, so it is our job to take care of the "Temple" the LORD has entrusted us with as best we can. Still, through Christ's work on the cross, we are seen as flawless beings. Straight hair, curly hair, large nose, small nose...we are equal beauties in His sight. And through Christ's work on the cross, our insecurities don't have to be a burden anymore.
What are your insecurities? Your face? Your hair? Your voice? Stop fretting about them and leave the thing that plagues you, because it's not perfect, on the cross. Chances are it's flawless in God's sight! :)
