Your worth is not determined by man. God has already established our worth in His Word.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. John 3:16
If God says that you are worth Him sending His ONLY Son to die for your sins, what more proof do you need? The next time someone questions your worth, tell that person, “The opinion of an irrelevant person pales in comparison to the opinion of a RELEVANT GOD. I am what God says I am!”
