Three billion souls in the kingdom of God sounds astronomical, until you realize that there used to be nine billion people on the planet, two billion of whom have already been killed physically and/or spiritually. Another one million of them are on the verge of self-destruction or self-annihilation within the next 24 hours.
Assuming that everyone heard about the kingdom of God, why is it that some chose not to enter? Perhaps they questioned their authenticity, perhaps they were fearful of rejection, or perhaps they prefer to be uncommitted to truth. Whatever the reason that they chose not to enter, they should know that if they ever have a change of heart, they will be welcomed into the eternal kingdom of God.
