People are complicated. Every day we have choices to make, and those choices shape how others see us, and more importantly how God sees us. Most first impressions are decided by outward appearances. That’s human nature. Thankfully, we can rest in the beautiful fact that God couldn’t care less what we look like, because He is looking at our hearts, and what is being reflected out of them. That is where He sees our beauty or lack thereof.
I hope as you grow to know Him better, you become more and more comfortable being who God created you to be, relying on Him for strength. I pray that for myself as well.
