The building of the tower represents what every human life ought to aim at, the rearing up of a strong, solid structure in which the builder may dwell and be at rest.

But then remember we are always building, consciously or unconsciously. By our transitory actions we are all rearing up a house for our souls in which we have to dwell; building character from out of the fleeting acts of conduct, which character we have to carry with us for ever. Soft invertebrate animals secrete their own shells. That is what we are doing-making character, which is the shield of self, as it were; and in which we have to abide.

My friend, what are you building? A prison; a mere garden-house of lustful delights; or a temple fortress in which God may dwell reverenced, and you may abide restful? Observe that whilst all men are thus unconsciously and habitually rearing up a permanent abode by their transient actions, every life that is better than a brute's ought to have for its aim the building up of ourselves into firm strength. The development of character is what we ought to ask from, and to secure by, this fleeting life of ours. Not enjoyment; that is a miserable aim. Not the satisfaction of earthly desires; not the prosperity of our business or other ordinary avocations. The demand that we should make upon life, and the aim which we should have clearly before us in all that we do, is that it may contribute to the formation of a pure and noble self, to the development of character into that likeness to Jesus Christ, which is perfection and peace and blessedness.

And while that is true about all life, it is eminently true in regard to the highest form of life, which is the Christian life. There are dreadful mistakes and imperfections in the ordinary vulgar conception of what a Christian is, and what he is a Christian for. What do you think men and women are meant to be Christians for? That they may get away from some material and outward hell? Possibly. That they may get celestial happiness? Certainly. But are these the main things? By no means. What people are meant to be Christians for is that they may be shaped into the likeness of Jesus Christ; or to go back to the metaphor of my text, the meaning and aim of Christian discipleship is not happiness, but the building up of the tower in which the man may dwell.

Ah, friend; is that your notion of what a Christian is; and of what he is a Christian for, to be like the Master? Alas! alas! how few of us, honestly and continually and practically, lay to heart the stringent and grand conception which underlies this metaphor of our Lord's, who identifies the man that was thinking of being His disciple with the man that sits down intending to build a tower.

II. So, secondly, note the cost of the building, or the conditions of discipleship.

Building is an expensive amusement, as many a man who has gone rashly in for bricks and mortar has found out to his cost. And the most expensive of all sorts of building is the building up of Christian character. That costs more than anything else, but there are a number of other things less noble and desirable, which share with it, to some extent, in the expenditure which it involves.

Discipleship demands constant reference to the plan. A man that lives as he likes, by impulse, by inclination, or ignobly yielding to the pressure of circumstances and saying, 'I could not help myself, I was carried away by the flood,' or 'Everybody round about me is doing it, and I could not be singular'—will never build anything worth living in. It will be a born ruin—if I may so say. There must be continual reference to the plan. That is to say, if a man is to do anything worth doing, there must be a very clear marking out to himself of what he means to secure by life, and a keeping of the aim continually before him as his guide and his pole-star. Did you ever see the pretty architect's plans, that were all so white and neat when they came out of his office, after the masons have done with them-all thumb-marked and dirty? I wonder if your Bibles are like that? Do we refer to the standard of conduct with anything like the continual checking of our work by the architect's intention, which every man who builds anything that will stand is obliged to practise? Consult your plan, the pattern of your Master, the words of your Redeemer, the gospel of your God, the voice of judgment and conscience, and get into the habit of living, not like a vegetable, upon what happens to be nearest its roots, nor like a brute, by the impulses of the unreasoning nature, but clear above these put the understanding, and high above that put the conscience, and above them all put the will of the Lord. Consult your plan if you want to build your tower.

Then, further, another condition is continuous effort. You cannot 'rush' the building of a great edifice. You have to wait till the foundations get consolidated, and then by a separate effort every stone has to be laid in its bed and out of the builder's hands. So by slow degrees, with continuity of effort, the building rises.

Now there has been a great deal of what I humbly venture to call one-sidedness talked about the way by which Christian character is to be developed and perfected. And one set of the New Testament metaphors upon that subject has been pressed to the exclusion of the others, and the effortless growth of the plant has been presented as if it were the complete example of Christian progress. I know that Jesus Christ has said: 'First the blade, then the ear; after that the full corn in the ear.' But I know that He has also said, 'Which of you, intending to build a tower'—and that involves the idea of effort; and that He has further said, 'Or what king, going to make war against another king'—and that involves the idea of antagonism and conflict. And so, on the whole, I lay it down that this is one of the conditions of building the tower, that the energy of the builder should never slacken, but, with continual renewal of effort, he should rear his life's building.
