"Even when you say i'm not, He says I'm beautiful.
In 1 Samuel 16:7, when God instructed Samuel to go anoint the next king of Israel, He tells him not to consider [the next king's] APPEARANCE or his height because the He had rejected him [who had those things]. He then says: "The Lord does not look at the things people look at. People look at the OUTWARD appearance, but the Lord looks at the heart."
When we start looking to God as our foundation of beauty, nothing in this world can hinder the truths that rest in us, and when lies do start to enter our lives, we know that we have a resting place to run to, a God who is comforting, reassuring, full of truth, and never changing (Malachi 3:6a "I the Lord do not change).
No matter what they say, YOU are beautiful :)
