“It is not possible that you will repent unless you are aware of your sin; it is not likely that you will look to Christ unless you first know what it is for which you are to look to him. Therefore, I pray you, set apart some season every day, or at least some season as often as you can get it, in which the business of your mind shall be to take your longitude and latitude, that you may know exactly where you are. You may be drifting towards the rocks, and you may be wrecked before you know your danger. I implore you, do not let your ship go at full steam through a fog; but slacken speed a bit, and heave the lead, to see whether you are in deep waters or shallow. I am not asking you to do more than any kind and wise man would advise you to do; do I even ask you more than your own conscience tells you is right? Sit alone a while, that you may carefully consider your case.”
