Stand Firm in the Truth

The commission God has given to His Church in this age may even be beyond what our human minds can fully comprehend at this time! The mystery of God has to be declared today. But this work is also to teach all humanity that the mystery must be dispensed, or declared, to every person ever created. They must be taught not just the mystery, but taught to teach it. Why? Is it possible God will keep expanding His Family throughout the universe forever?
