People who are in the rut, the circular grave, find that it is getting harder for them to change. They used to have spells when they were emotionally moved. Their wills got over on the side of God, and they really meant to make themselves into good Christians by the grace of God. But those times are getting fewer. They cannot afford to wait and say, "Oh, well, I will do it next Thanksgiving. I'll do it when I come home from vacation." No, they will either do it now or they will not do it at all. There comes a time when they must make a change. If they do not make it, they never will. Time is stealing away their days of opportunity to make it. They began with a given number of days, and they have already used up so many days. But the tragedy is that they do not know how many remain. They do not know how many they have left because they do not know how many they had to start with. While they could count the number of days they have been on the earth, they do not know how that stacks up to the number accorded them, so they do not know where they are. They only know that the days are doing what the poet said about the leaves. "The leaves of life keep falling one by one."
