IT is well to understand that “the kingdom of the heavens” does not mean heaven itself but its reign over the earth while the King rejected by man is seated on high. The six later parables present successive comparisons of that kingdom in its chief characteristics: three are its public aspect, and so, like the first, were addressed without to the great multitudes; the three last, like the explanation of the first similitude, or Parable of the Darnel, were spoken in the house only to the disciples, as dealing with what needed spiritual intelligence.
Another distinction is obvious. The Parable of the Mustard Seed, like that of the Leaven, shows what the kingdom is like, in marked difference from its predecessor, as it becomes more apparent still in its successor.
“The kingdom of the heavens is like a grain of mustard which a man took and sowed in his field; which is less than all the seeds, but, when it hath grown, is greater than the herbs, and becometh a tree so that the birds of heaven come and roost in its branches” (vers. 31, 32).
Here the Lord gives us to see the least and lowliest beginning of Christian profession growing to be a power in the earth. In Luke 17:66And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you. (Luke 17:6), He employs the same figure of a grain of mustard; as indeed it was a proverbial expression for what is diminutive. But the grain soon shot up so as to leave the pot-herbs behind, and afford shelter to the birds it notoriously attracts.
So it was to be, so it has long been, with that which bears His name here below. The Lord marks beforehand the surprising contrast between the extreme littleness of its first estate when sown, and the height to which it was ere long to advance. He is not here pronouncing on its inner or moral nature. He shows from the first what all the world can see when it came to pass. It is one of “the mysteries (or secrets) of the kingdom of the heavens,” but secrets given for the disciples to know. And the Lord here sets out the fact, in due time palpable to all mankind, that what began the most minute was to develop into a conspicuous and protective power on the earth, according to the well known figure of a nation or political system in Isa. 11:33, 34; Ezek. 31; Dan. 4, &c.
Now this was no mystery for Israel any more than for the Gentile powers. It was expressly allotted to the ancient people of God, as we read in the Psalms and the Prophets. So in the days of depression when captivity befell “the rebellious house,” God made use of a tree to illustrate His ways with them, and their ways before Him which drew out His sternest chastening. But He adopted the same figure to assure the believing heart that in His mercy all will be reversed in the day to come, and that He will plant the tender twig on a mountain high and eminent, even the height of Israel. “And it shall bring forth boughs and bear fruit, and be a goodly cedar; and under it shall dwell all birds of every wing; in the shadow of the branches thereof shall they dwell. And all the trees of the field shall know that I Jehovah have brought down the high tree, have exalted the low tree, have dried up the green tree, and have made the dry tree to flourish: I Jehovah have spoken and will do it” (Ezek. 17). It is all of His mercy; but how could the result in this case be otherwise? For Jehovah of hosts shall reign in mount Zion, and in Jerusalem and before His ancients gloriously.
Wholly different was to be the proper portion of the Christian on earth. “Blessed are the poor in spirit; for theirs is the kingdom of the heavens. Blessed are they that mourn; for they shall be comforted. Blessed are the meek; for they shall inherit the earth...Blessed are they that have been persecuted for righteousness' sake, for theirs is the kingdom of the heavens. Blessed are ye when they shall reproach you and persecute you and say all manner of evil against you falsely for my sake. Rejoice and be exceeding glad; for great is your reward in heaven; for so persecuted they the prophets that were before you” (Matt. 5:3-123Blessed are the poor in spirit: for theirs is the kingdom of heaven. 4Blessed are they that mourn: for they shall be comforted. 5Blessed are the meek: for they shall inherit the earth. 6Blessed are they which do hunger and thirst after righteousness: for they shall be filled. 7Blessed are the merciful: for they shall obtain mercy. 8Blessed are the pure in heart: for they shall see God. 9Blessed are the peacemakers: for they shall be called the children of God. 10Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven. 11Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake. 12Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you. (Matthew 5:3‑12)). Even those whom God set first in the church were expressly charged by our Lord against power and glory of an earthly sort. “Ye know that the rulers of the Gentiles lord it over them, and their great ones exercise authority over them. Not so shall it be among you. But whosoever would become great among you shall be your servant; and whosoever would be first among you, let him be your slave: even as the Son of man came not to be served, but to serve, and to give his life a ransom for many” (Matt. 20:25-2825But Jesus called them unto him, and said, Ye know that the princes of the Gentiles exercise dominion over them, and they that are great exercise authority upon them. 26But it shall not be so among you: but whosoever will be great among you, let him be your minister; 27And whosoever will be chief among you, let him be your servant: 28Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many. (Matthew 20:25‑28)).
Thus the Lord lets us know in this parable that, in the face of His revealed will, Christendom would soon manifest a portentous change, and from its primitively low estate vie with the powers of the world in earthly grandeur and influence. We are called now to walk apart from the world, its power and its glitter, content to be hated as our Master was (John 15), cherishing also the secret of God's grace and the relationships it gives us, and suffering with Christ meanwhile. “But if children, then heirs; heirs of God, and joint-heirs with Christ: if so be that we suffer with Him, that we may be also glorified with Him” (Rom. 8). “Faithful is the saying: for if we died with Him, we shall also live with Him; if we endure, we shall also reign with Him” (2 Tim. 2:11, 1211It is a faithful saying: For if we be dead with him, we shall also live with him: 12If we suffer, we shall also reign with him: if we deny him, he also will deny us: (2 Timothy 2:11‑12)). Now is the time for us to have tribulation in the world, till He come to take us to the Father's house, and we be manifested also with Him in glory when He is manifested. The day of glory with Christ will make ample amends.
But how is it with you, dear reader? Is Christ the object of your faith? If so, it is well indeed with you now and evermore. If He is nothing to you beyond any other whom men discuss, notwithstanding God's testimony to Him, it were better for you that you had not been born. Refusing God's light and love in Him Who went down below all depths for sinners, you cannot escape the judgment which He will execute on all the impenitent and unbelieving, that despise Him and the saving grace of God in Him. Before that everlasting judgment there shall be a day of Jehovah of hosts upon all that is proud and mighty, and upon all that is lifted up; and it shall be brought low. Jehovah alone shall be exalted in that day. Meanwhile God commandeth men that they should all everywhere repent. Oh, that His goodness may lead you to repentance! The time is short: delay not. Your sins are many and great. The blood of Jesus Christ His Son cleanseth from every sin: nothing else can.
