The first point that I would insist upon is a well-worn and familiar one, as I am well aware, but I urge it upon you, and especially upon the younger portion of my audience. It is this, that there is no telling the amount of mischief that pure weakness of character may lead into. The worst men we come across in the Bible are not those who begin with a deliberate intention of doing evil. They are weak creatures, 'reeds shaken by the wind,' who have no power of resisting the force of circumstances. It is a truth which every one's experience confirms, that the mother of all possible badness is weakness, and that, not only as Milton's Satan puts it, 'To be weak is to be miserable,' but that weakness is wickedness sooner or later. The man who does not bar the doors and windows of his senses and his soul against temptation, is sure to make shipwreck of his life and in the end to become 'a fool.' There is so much wickedness lying round us in this world that any man who lets himself be shaped and coloured by that with which he comes in contact, is sure to go to the bad in the long run. Where a man lays himself open to the accidents of time and circumstances, the majority of these influences will be contrary to what is right and good. Therefore, he must gather himself together and learn to say 'No!' There is no foretelling the profound abysses into which a 'good, easy' nature, with plenty of high and pure impulses, perhaps, but which are written in water, may fall. 'Thou, therefore, young man! be strong in the grace that is in Christ Jesus.' Learn to say No! or else you will be sure to say Yes! in the wrong place, and then down you will go, like this Joash whose goodness depended on Jehoiada, and when he died, all the virtue that had characterised this life hitherto was laid with him in the dust.
