What did Jesus mean when He spoke of the kingdom of God? The idea as set forth in the Gospels is so complex, the phrase is used to cover so many and different conceptions, that it is practically impossible to frame a definition within which all the sayings of Jesus concerning the kingdom can be included. The nearest approach to a definition which it is necessary to attempt is suggested by the two petitions in the Lord's Prayer which are quoted above. The second petition explains the first: the kingdom comes in proportion as men do on earth the will of God. For our present purpose, therefore, we may think of the kingdom as a spiritual commonwealth embracing all who do God's will. To much that Christ taught concerning the kingdom--its Head, its numbers, its growth and development--it is impossible, in one brief discourse, even to refer. Here again, it must suffice to single out one or two points for special emphasis:
(1) In the doctrine of the kingdom of God, we have set before us the social aspect of Christ's teaching; it reminds us of what we owe, not only to Him who is its King, but to those who are our fellow-subjects. Of particular duties it is impossible to speak, though these, as we know, fill a large place in the teaching of Jesus. But let us at least bring home to ourselves the thought of obligation, obligation involved in and springing out of our common relationship as members of the kingdom of God. The obligation is writ large on every page of the New Testament--in the Gospels, in the doctrine of the kingdom; in the Epistles, in the corresponding doctrine of the Church. It can hardly be said too often, that, according to the New Testament ideal, there are no unattached Christians. The apostles never conceive of religion as merely a private matter between the soul and God. All true religion, as John Wesley used to say, is not solitary but social. Its starting-point is the individual, but its goal is a kingdom. Christ came to save men and women in order that through them He might build up a redeemed society in which the will of God should be done. We do, indeed, often hear of Christians whose religion begins and ends with getting their own souls saved. This simply means that so far as it is true they are not yet Christian. To think only of oneself is to deny one of the first principles of the kingdom. Wesley taught the early Methodists to sing--
"A charge to keep I have.
A God to glorify;
A never-dying soul to save,
And fit it for the sky;"
and some of his followers, both early and later, seem to have thought that this was the whole of the hymn; but the verse goes on without a full stop--
"To serve the present age,
My calling to fulfil;
O may it all my powers engage
To do my Master's will!"
And until we who profess and call ourselves Christians have learned this lesson of service, and have entered into Christ's thought of the kingdom, with its interlacing network of obligations, we have still need that some one teach us again the rudiments of the first principles of the oracles of God.
(2) Again, the kingdom of God, Christ taught, is present; it is not of, but it is in, this world, set up in the midst of the existing order of things. There are, it is true, passages in which Christ speaks of the kingdom as in the future, and to come. Thus, e.g., He speaks of a time when men "shall come from the east and west, and from the north and south, and shall sit down in the kingdom of God"; when "the righteous shall shine forth as the sun in the kingdom of their Father"; when they shall "inherit the kingdom prepared for" them "from the foundation of the world"; and so forth. But there is no real contradiction between this and what has been already said. The kingdom is a growth, a movement working itself out in history, and therefore it may be said to be past, present, or future, according to our point of view. In the sense that it has not yet fully come, that its final consummation is still waited for, it is future; and so sometimes Christ speaks of it. But it is simply impossible to do justice to all His sayings and deny that in His thought the kingdom is also present. Its consummation may belong to the future, its beginnings are here already. When Christ calls it the kingdom of heaven, it is rather its origin and character that are suggested than the sphere of its realization. In parable after parable He speaks of it as a secret silent energy already at work in the world. He called on men here and now to seek it, and to enter it. So eagerly were the lost and the perishing pressing into it that once He declared that from the days of John the Baptist the kingdom of heaven suffered violence. Not in some future heaven but here "on earth" He bade His disciples pray that God's will might be done. "When Jesus said the kingdom of heaven, be sure He did not mean an unseen refuge, whither a handful might one day escape, like persecuted and disheartened Puritans fleeing from a hopeless England, but He intended what might be and then was in Galilee, what should be and now is in England."[30] "Thy kingdom come"--it is here on earth we must look for the answer to our prayer. And every man who himself does, and in every possible way strives to get done, God's will among men, is Christ's co-worker and fellow-builder.
"I will not cease from mental fight,
Nor shall my sword sleep in my hand,
Till we have built Jerusalem
In England's green and pleasant land."
That is the spirit of all the true servants of Jesus.
(3) But the most important fact concerning the kingdom in Christ's view of it is that it is spiritual. And, because it is spiritual, it failed wholly to satisfy the earth-bound ambitions of the Jews. For generations they had fed their national pride with visions of a world obedient to Israel's sway, and when one who claimed to be the Messiah nevertheless told them plainly that His kingdom was not of this world, they turned from Him as from one that mocked. He and they both spoke of a kingdom of God, but while they emphasized the "kingdom" He emphasized "God." So wholly did men fail to enter into His mind that on one occasion two of His own disciples came to Him asking that they might sit, one on the right hand, and one on the left hand in His glory. And even when He was just about to leave them, and to return to His Father, the old ambitions still made themselves heard. "Lord," said they, "dost Thou at this time restore again the kingdom to Israel?" But with all such dreams of temporal sovereignty Christ would have nothing to do; He had put them from Him, definitely and for ever, in the Temptation in the wilderness. He completely reversed the current notions concerning the kingdom. "Being asked by the Pharisees when the kingdom of God cometh, He answered them and said, The kingdom of God cometh not with observation; neither shall they say, Lo, here! or, There! for lo, the kingdom of God is within you." And when self-complacent religious leaders flattered themselves that, of course, the first places in the kingdom would be theirs, He sternly warned them that they might find themselves altogether shut out while the publicans and harlots whom they despised were admitted. Through all His teaching Christ laid the emphasis on character. Pride, and love of power, and sordid ambitions, and all self-seeking--for these things, and for them that cherished these things, the kingdom had no place. "Blessed," Christ said, "are the poor in spirit: for theirs is the kingdom of heaven." "Except ye turn, and become as little children, ye shall in no wise enter into the kingdom of heaven." "Whosoever would become great among you, shall be your minister; and whosoever would be first among you shall be servant of all"--these are they that are accounted worthy of the kingdom of God.
