Think for a moment about how we mark the passage of time in our lives. We all know how old we are. Students know what grade they are in. Workers know how long they have been employed. Married people count their anniversaries. Some of us remember America’s bicentennial. Perhaps we pay attention to such markers to try to make sense of the meaning of our lives as those caught up in the inevitable cycle of birth and death, of one generation passing away as another arises. As we read in Ecclesiastes, “That which has been is what will be, That which is done is what will be done, and there is nothing new under the sun.” (Eccles. 1:9)
