Esau had sold his birth-right as firstborn for a cup of curry (Genesis 25:29-33). And when Jacob got blessings from his father Isaac (Genesis 27:27-30), Esau roared out with a great cry (27:34) and start hated Jacob (27:41). 

     But as a new born Christian your birth-right cannot be Bartered/ Steal/ Snatch because Jesus has paid the full price on Cross. We all Christians are Firstborn (Hebrew 12:23).
