It saddens me when people post pictures on social media, and after ask friends to tell them how they look or to rate their beauty. Also some with very dark skins will post pictures, and after say "black is beauty "or "I'm proud of my color", these are lies and insecurities. Sorry to say this, but this is common among ladies, and is the spirit of insecurity from the devil.
When you ask others to rate your beauty, it means you are questioning and not sure about what God has said and declared concerning you; you are carrying His own image and likeness, and not only that, He said you are good, which means He created you perfectly. The same thing applies to those of you not comfortable of your skin tones.
This spirit of insecurity was what Satan put into Eve, and made her to feel she wasn't what God really said about her, which led her to sin. Even in those days, Satan still put that spirit of insecurity on many people especially the ladies to make them feel that they were not what God said about them.
This spirit of insecurity, has led many to corrupt the very image and likeness of God in them.
Secondly, some don't trust the beauty that God has spoken about them, so they go and edit that beauty.
The psalmist said in Psalm 139:14, that he is fearfully and wonderfully made, let this be your confession, and stop seeking the approval of men. It Is not about what others say about you, but what God has already said; you are beautiful and unique.
God bless you
