Read Psalms 45:6  We don't have kings here in America.  We have presidents and we have governors of the states that we elect.  A king rules differently.  He is not elected; he is the king because his father was the king.  When a king grows older, his son is in line to become the next king.  If a king has several sons, they are all known as princes.  But the oldest is known as the crown prince because he will soon be the next king.  Sometimes kings reign for a long time, but they eventually die and the throne passes down to one of their sons.  But our verse today says that God's throne is forever.  He never grows old and He never dies.  He never has to prepare for the next king because He has always been the King, and He will always be the King!  God lives forever.  Isn't it good that we can trust in a God Who never grows old and Who will never die!  The scepter  is the thing that the king holds that is the symbol of his authority.  God is forever on His throne and his scepter is for ever and for ever!
