In one sense the kingdom of God belongs to the future age. It is never realized fully upon earth; there is here always some lurking trace of sinful resistance. Nevertheless, in the New Testament the kingdom is by no means always represented as future. Though it has not yet been fully realized, it is already present in principle; it is present especially in the Church. The Church gives clear, though imperfect, expression to the idea of the kingdom; the Church is a people whose ruler is God.
Entrance into the Church is not to be obtained by human effort; it is the free gift of God through the Lord Jesus Christ. No other gift is so glorious. If we are members of that chosen people, we need fear nothing in heaven or on earth.
2. PRACTICAL CONCLUSIONS
Two lessons should be conveyed by our study of to-day: in the first place the lesson of separateness, and in the second place the lesson of unity. Neither can be truly learned without the other. There can be no true Christian unity if individual members of the Christian body make common cause with the unbelieving world. A knowledge of the common enemy will draw us all into closer fellowship. That fellowship need not necessarily be expressed in a common organization; but it will be expressed at least in a common service. Separateness from the world will not mean leaving the world to its fate; the Christian salvation will be offered freely to all. But the gravity of the choice should never, by any false urbanity, be disguised. It is no light difference whether a man is within the people of God or without; there is a definite line of demarcation, and the passing of it means the transition from death into life.
