The Kingdom of God is the new reality that we must press in to. It’s not something that we are awaiting to come, it has already come. It’s not some flickering hope in the dim future, it’s currently within our grasp now.
A key component to understanding the “when” of the kingdom is to have a firm understanding of the way that the Bible talks about time and the way that it is divided. Scripture makes mention of two ages: the age that is and the age that is to come.
