Christ's promise can never fail. He has, blessed be His name, come down to the lowest possible point by which the assembly can be represented, even "_two_." How gracious! How tender! How considerate! How like Himself! He attaches all the dignity--all the value--all the efficacy of His own divine and deathless name to an obscure handful gathered round Himself. It must be very evident to the spiritual mind that the Lord Jesus, in speaking of the "two or three" thought not of those vast systems which have sprung up in ancient, mediaeval, and modern times, throughout the eastern and western world, numbering their adherents and votaries, not by "twos or threes," but by kingdoms, provinces, and parishes. It is very plain that a baptized kingdom, and "two or three" living souls gathered in the name of Jesus, do not and cannot mean the same thing. Baptized Christendom is one thing, and the assembly of God is another. What this latter is, we have yet to unfold; we are here asserting that they are not, and cannot be, the same thing. They are constantly confounded, though no two things can be more distinct.[XXI.] If we would know under what figure Christ presents the baptized world, we have only to look at the "leaven" and the "mustard tree" of Matt. xiii. The former gives us the internal, and the latter the external character of "the kingdom of heaven"--of that which was originally set up in truth and simplicity--a real thing, though small, but which, through Satan's crafty working, has become inwardly a corrupt mass, though outwardly a far-spreading, showy, popular thing in the earth, gathering all sorts beneath the shadow of its patronage. Such is the lesson--the simple but deeply solemn lesson to be learnt by the spiritual mind from the "leaven" and the "mustard-tree" of Matt. xiii. And we may add, one result of learning this lesson would be an ability to distinguish between "the kingdom of heaven" and "the assembly of God." The former may be compared to a wide morass, the latter to a running stream passing through it, and in constant danger of losing its distinctive character, as well as its proper direction, by intermingling with the surrounding waters. To confound the two things is to deal a deathblow to all godly discipline and consequent purity in the assembly of God. If the kingdom and the assembly mean one and the same thing, then how should we act in the case of "that wicked person" in I Cor. v.? The apostle tells us "to put him away." Where are we to put him? Our Lord Himself tells us distinctly that "the field is _the world_;" and again, in John xvii., He says that His people are not of the world. This makes all plain enough. But men tell us, in the very face of our Lord's statement, that the field is the assembly, and the tares and wheat, ungodly and godly, are to grow together, that they are on no account to be separated. Thus the plain and positive teaching of the Holy Ghost in I Cor. v. is set in
