There are several words in the Greek language which translate into the English word for time. Chronos is the one we would find most familiar, meaning successive or sequential time, the kind of time you find on your wristwatch.
Another is Kairos, meaning an event, an opportunity – a moment in time when perhaps everything changes because it is the right time.
Your emotions are often a great indicator of kairos events and it is often the negative events producing negative emotions that present the greatest potential for growth.
