+Origin of the idea of the Kingdom of God.+--At the time when Jesus came every person of Jewish nationality was looking for the establishment of what had come to be called the Kingdom of God. For many generations the Jews had been a subject race. There had been one brief period of national splendour and prosperity, namely, the reigns of David and Solomon. After generations were inclined to idealise these two reigns, especially the former, and to look upon them as a kind of golden age. David they looked upon as an ideal monarch; they called him a "man after God's own heart," and the imagination of poet and prophet loved to dwell upon his winsome personality. They thought of him as in a special way the king chosen by God, and the Israel of his time as a true kingdom of God, a kingdom of righteousness, peace, and plenty under the favour of the Most High. The real Israel of David's day was far different from this, but compared with the days that followed it was indeed a time of unexampled greatness. A similar tendency to idealise the past is observable in nearly every nation which has entered upon a period of suffering or misfortune, as we can see from the legends about King Olaf and Frederick Barbarossa. But Israel always looked upon herself as in a special way a theocratic kingdom, a chosen of God. At its best this idea was a fine one, one, it led to the thought of a special spiritual vocation for the sake of the other nations of the earth; at its worst it meant the assertion of national privilege and contempt for everything which was not Jewish. After the great captivity in Babylon the Jews were never without a foreign master, and the northern kingdom of Israel disappeared from history. But in quite a remarkable way Jewish poets and preachers united to keep alive the popular belief that God would yet "restore the kingdom to Israel." Hence there grew up a firmly held conviction that God would sometime raise up a prince born of David's line who with supernatural help, and with a strong hand, would drive out the invader and establish a kingdom which should outshine even that of David himself. This was the root idea of the kingdom of God, as we meet it in the New Testament, and as it is described in some of the most beautiful passages of the Old.
