This being clearly understood at the outset, we shall be prepared to follow the Apostle's course of thought while he points out the conditions upon which the possession of that inheritance depends. It is children of God who are heirs of God. It is by union with Christ Jesus, the Son, to whom the inheritance belongs, that they who believe on His name receive power to become the sons of God, and with that power the possession of the inheritance. Thus, then, in this condensed utterance of the text there appear a series of thoughts which may perhaps be more fully unfolded in some such manner as the following, that there is no inheritance without sonship, that there is no sonship without a spiritual birth, that there is no spiritual birth without Christ, and that there is no Christ for us without faith. I. First, then, the text tells us, no inheritance without sonship. In general terms, spiritual blessings can only be given to those who are in a certain spiritual condition. Always and necessarily the capacity or organ of reception precedes and determines the bestowment of blessings. The light falls everywhere, but only the eye drinks it in. The lower orders of creatures are shut out from all participation in the gifts which belong to the higher forms of life, simply because they are so made and organised as that these cannot find entrance into their nature. They are, as it were, walled up all round; and the only door they have to communicate with the outer world is the door of sense. Man has higher gifts simply because he has higher capacities. All creatures are plunged in the same boundless ocean of divine beneficence and bestowment, and into each there flows just that, and no more, which each, by the make and constitution that God has given it, is capable of receiving. In the man there are more windows and doors opened out than in the animal He is capable of receiving intellectual impulses, spiritual emotions; he can think, and feel, and desire, and will, and resolve: and so he stands on a higher level than the beast below him.
