Young and then suddenly--old

I was talking today to a group of friends about the day I realized I really am a senior citizen. "I told my family," I shared, "'Seems like just a few days ago I was a teenager. How did I get old so quickly?'" I then shared that suddenly I am understanding that when Jesus said, "Behold, I come quickly," it's true. Our lives pass so fast if Jesus returns to earth today it will be "quickly" because when we think about it, if we added up all the generations from the time Jesus walked the earth until now, because life is here and gone so fast, His Second Coming, indeed, will be "quickly." One of the women recalled that a Sunday school teacher shot a puff of hair spray into the air and watched until it disappeared. "That's like our lives. We're here, then we're gone." the teacher said. The Bible compares our lives to a "vapor." "Now listen, you who say, 'Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money. Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes. Instead, you ought to say, 'If it is the Lord's will, we will live and do this or that.' As it is, you boast and brag. All such boasting is evil. Anyone, then, who knows the good he ought to do and doesn't do it, sins" (James 4:13-17NIV.)
