1 John 3:1 

Behold what manner of love the Father has bestowed on us, that we should be called children of God! Therefore the world does not know us, because it did not know Him.

Behold, the heart of our Heavenly Father, His love toward you, that He has called you His child. 

It's no wonder we don't fit into this world's system and ideas. Our identity is from God, the Creator Himself.
