If holiness be not merely the doing a certain number of good actions, but is an inward character which follows, under God's grace, from doing them, how far distant from that holiness are the multitude of men! They are not yet even obedient in outward deeds, which is the first step towards possessing it. They have even to learn to practise good works, as the means of changing their hearts, which is the end. It follows at once, even though Scripture did not plainly tell us so, that no one is able to prepare himself for heaven, that is, make himself holy, in a short time;—at least we do not see how it is possible; and this, viewed merely as a deduction of the reason, is a serious thought. Yet, alas! as there are persons who think to be saved by a few scanty performances, so there are others who suppose they may be saved all at once by a sudden and easily acquired faith.

Most men who are living in neglect of God, silence their consciences, when troublesome, with the promise of repenting some future day. How often are they thus led on till death surprises them! But we will suppose they do begin to repent when that future day comes. Nay, we will even suppose that Almighty God were to forgive them, and to admit them into His holy heaven. Well, but is nothing more requisite? are they in a fit state to do Him service in heaven? is not this the very point I have been so insisting on, that they are not in a fit state? has it not been shown that, even if admitted there without a change of heart, they would find no pleasure in heaven? and is a change of heart wrought in a day? Which of our tastes or likings can we change at our will in a moment? Not the most superficial. Can we then at a word change the whole frame and character of our minds? Is not holiness the result of many patient, repeated efforts after obedience, gradually working on us, and first modifying and then changing our hearts?

We dare not, of course, set bounds to God's mercy and power in cases of repentance late in life, even where He has revealed to us the general rule of His moral governance; yet, surely, it is our duty ever to keep steadily before us, and act upon, those general truths which His Holy Word has declared. His Holy Word in various ways warns us, that, as no one will find happiness in heaven, who is not holy, so no one can learn to be so, in a short time, and when he will. It implies it in the text, which names a qualification, which we know in matter of fact does ordinarily take time to gain.
