Becomes head of the family upon death of the father.
Double portion of the inheritance
Father's Blessings - spiritually, physically
First right to the use of his name
Second in command, next to the father
always on the right hand-side of the father
co-reign with Him - dominion
Every Christian that accepts the miracle of Salvation becomes "born-again" and receives his/her birthright as a firstborn in Christ. When your spirit understands and accepts being His firstborn, then by faith, you can claim and use your "birth rights". Glory to God
