In fact, you are now entering upon the most important period--the _turning point_--of your whole life. You have become, in a great measure, your own master. For though you will be under a certain degree of discipline and _surveillance_, yet in a multiplicity of cases you will have to act for yourself--to take your own line. You will have to contend against the allurements of pleasure and dissipation, and you have just reached the age when the natural passions and appetites become most impatient of restraint. At the same time, you will be exposed to the influence both of the example and of the solicitations of lively young men, who will try to carry you along with them in their career of thoughtlessness and folly, and who will think it strange, and _show_ you that they think it strange, if you run not with them to the same excess of riot. Against all these moral trials and temptations, your best safeguard will be found in a strong sense of religion, kept habitually present to your mind. You must endeavour, according to the language of Scripture--(and in writing to you I shall always gladly make use of the very words of Scripture, when they suit my purpose, as having a force and an authority which no other words can possess)--you must endeavour to _set the Lord always before you_. Never for a moment forget that you are continually in the presence of that awful Being, who can, and who will, call you to a strict account for all that you do amiss. Nothing can excuse your forgetting Him. If you at all believe in a Supreme Being, the Creator and Governor of the world; if you believe that God is, and that he is a rewarder of them that diligently seek him, and at the same time an avenger to execute wrath upon every soul that doeth evil, the least particle of common sense or common feeling will tell you, that nothing should be put in competition with his will. When his will is clear, it _must_ be obeyed without hesitation. I am sure that you will assent to this. If religion is any thing, it is _every thing_. It is, indeed, the one thing needful, in comparison with which every thing else sinks into insignificance, into nothingness. Endeavour, then, to keep up in your mind and heart this habitual sense of religion by every means in your power. It will require from you considerable care and attention. The lively spirits natural to your time of life, and the thoughtless levity of some of the young men into whose society you will be thrown, will have a tendency to make you think less of religion, if not to induce you entirely to forget it. Be ever on your guard against thus swerving from your allegiance to your Creator.
