people don't know the purpose of life!

Tuesday my daughter made a video here in our city. She asked people on the street, “What is the purpose of your life?” I almost wanted to cry when I watched the video. Half the people admitted honestly that they had no answer to this question. The rest made guesses; gave cliched answers like, "to be happy" or "to live for our children”. Not a single one had an answer that they gave full of conviction or certainty! How sad that people "live" like this, without the answer to life's most fundamental question. God help them!
