"I have a watch here with me.
Now the purpose of a watch is to tell time - it cannot sweep the floor, or do something else. What it does best is to tell the time.
Same goes with us.
God create us with the sole purpose of enjoying a relationship with Him. But we fill our lives with money... with work, or studies achievements. With temporal pleasures.
Our purpose goes unfulfilled."
And so we become like a watch wanting to wash the dishes or something.
