You are Unique
For we are God’s masterpiece. He has created us anew in Christ Jesus, so we can do the good things he planned for us long ago. Ephesians 2:10 NLT
Your identity is defined by God, not your feelings. You were created and designed by a loving Father with unique gifts and abilities, interests and appearance. You don't need the world's approval - you have already been approved by God.
A secular worldview will never give you the value you were designed to have. A Christian worldview knows you have infinite value and are not a random act but a divinely created masterpiece.
