This is a prophecy. The singer is looking on. The order of the earthly realisation of the Kingdom of God is seen as established. First, the city is contemplated at the centre of everything, with Jehovah as its God. Then the peoples of the earth are seen in their true relation to that city.
It is a most remarkable utterance. Though brief, it is as comprehensive and full of beauty as any of the inspired predictions. Without specific statement, the sovereingty of God is taken for granted. There is no argument given for this. It is a fact beyond dispute and needing no proof. Thus God has the city of His chosen people as the centre and foundation of His administration. His love is set upon the city, and her fame is wide-spread; glorious things are spoken of her. The outcome is seen in the effect produced upon the surrounding peoples. Her ancient enemies are finally to be born, that is realise their true life, through this governing city of God.
This is the highest function of the chosen people according to the purpose of God. Under His government they are to bring the other nations to Him, so that they also shall find their highest in His Kingdom. This is not a story of Israel conquering by force of arms, but of that higher victory not yet won, when by manifestation and administration of the Divine government, the peoples shall dance and sing in the finding of their fountains and fulness in God.
