The explanation has partly been given already. It lies still further, however, in the meaning of the word Salvation. And this, of course, is not at all Salvation in the ordinary sense of forgiveness of sin. This is one great meaning of Salvation, the first and the greatest. But this is spoken to people who are supposed to have had this. It is the broader word, therefore, and includes not only forgiveness of sin but salvation or deliverance from the downward bias of the soul. It takes in that whole process of rescue from the power of sin and selfishness that should be going on from day to day in every human life. We have seen that there is a natural principle in man lowering him, deadening him, pulling him down by inches to the mere animal plane, blinding reason, searing conscience, paralyzing will. This is the active destroying principle, or Sin. Now to counteract this, God has discovered to us another principle which will stop this drifting process in the soul, steer it round, and make it drift the other way. This is the active saving principle, or Salvation. If a man find the first of these powers furiously at work within him, dragging his whole life downward to destruction, there is only one way to escape his fate--to take resolute hold of the upward power, and be borne by it to the opposite goal. And as this second power is the only one in the universe which has the slightest real effect upon the first, how shall a man escape if he neglect it? To neglect it is to cut off the only possible chance of escape. In declining this he is simply abandoning himself with his eyes open to that other and terrible energy which is already there, and which, in the natural course of things, is bearing him every moment further and further from escape.
From the very nature of Salvation, therefore, it is plain that the only thing necessary to make it of no effect is neglect. Hence the Bible could not fail to lay strong emphasis on a word so vital. It was not necessary for it to say, how shall we escape if we trample upon the great salvation, or doubt, or despise, or reject it. A man who has been poisoned only need neglect the antidote and he will die. It makes no difference whether he dashes it on the ground, or pours it out of the window, or sets it down by his bedside, and stares at it all the time he is dying. He will die just the same, whether he destroys it in a passion, or coolly refuses to have anything to do with it. And as a matter of fact probably most deaths, spiritually, are gradual dissolutions of the last class rather than rash suicides of the first.
This, then, is the effect of neglecting salvation from the side of salvation itself; and the conclusion is that from the very nature of salvation escape is out of the question. Salvation is a definite process. If a man refuse to submit himself to that process, clearly he cannot have the benefits of it. _As many as received Him to them gave He_ power _to become the sons of God._ He does not avail himself of this power. It may be mere carelessness or apathy. Nevertheless the neglect is fatal. He cannot escape because he will not.
Turn now to another aspect of the case--to the effect upon the soul itself. Neglect does more for the soul than make it miss salvation. It despoils it of its capacity for salvation. Degeneration in the spiritual sphere involves primarily the impairing of the faculties of salvation and ultimately the loss of them. It really means that the very soul itself becomes piecemeal destroyed until the very capacity for God and righteousness is gone.
The soul, in its highest sense, is a vast capacity for God. It is like a curious chamber added on to being, and somehow involving being, a chamber with elastic and contractile walls, which can be expanded, with God as its guest, illimitably, but which without God shrinks and shrivels until every vestige of the Divine is gone, and God's image is left without God's Spirit. One cannot call what is left a soul; it is a shrunken, useless organ, a capacity sentenced to death by disuse, which droops as a withered hand by the side, and cumbers nature like a rotted branch. Nature has her revenge upon neglect as well as upon extravagance. Misuse, with her, is as mortal a sin as abuse.
