(Although I have been teaching and writing books and articles on this subject for years, the following is based on notes I took from a teaching conducted by Dutch Sheets, who did a superb job of simplifying this message about the Kingdom of God.)
I. Genesis 1:28 gives us two aspects of the Cultural Mandate that God gave humanity: Multiply the family and manage the planet
Multiply a Family for God
In Genesis, the King of the kingdom (kingdom stands for “king” and “domain,” so the scope of a king’s rule is a kingdom) added a family to his kingdom realm when He made us.
The family mandate is to expand God’s family by Him creating eternal human spirits. Humankind is called to create eternal spirits because we are the only ones made in God’s image that can supply Him with family members (Genesis 1:28).
