If you believe in Jesus Christ and have accepted Him as your Lord and Savior, You are a Daughter of A King. 1 Peter 2:9 NIV says “But you are a chosen people, a royal priesthood, a holy nation, God's special possession, that you may declare the praises of him who called you out of darkness into his wonderful light.”
We are “Daughters of a King” because our Heavenly Father is the King of Kings and the Lord of Lords. WE. ARE. HIS.
