A person cannot know when the day and the hour of the kingdom of God will come, because its coming depends on themselves alone.
The answer is like that of the wise man who, when asked whether it was far to the town, answered, “Walk!”
How can we tell whether it is far to the goal which humanity is approaching, when we do not know how people are going toward it, while it depends on them whether they go or do not go, stand still, slacken their pace or hasten it? All we can know is what we who make up humanity ought to do, and not to do, to bring about the coming of the kingdom of God. And that we all know. And we need only each begin to do what we ought to do, we need only each live with all the light that is in us, to bring about at once the promised kingdom of God to which every person’s heart is yearning.
That is why that Power cannot require of us what is irrational and impossible: the organization of our temporary external life, the life of society or of the state. That Power demands of us only what is reasonable, certain, and possible: to serve the kingdom of God, that is, to contribute to the establishment of the greatest possible union between all living beings—a union possible only in the truth; and to recognize and to profess the revealed truth, which is always in our power.
“But seek ye first the kingdom of God, and his righteousness, and all these things shall be added unto you.” (Matthew 6:33)
The only significance of life consists in helping to establish the Kingdom of God; and this can be done only by means of the acknowledgement and profession of the truth by each one of us.
“The kingdom of God cometh not with outward show; neither shall they say, Lo here! or, Lo there! for behold, the kingdom of God is within you.” (Luke 12: 20, 21)
