TThe Greek language has a couple of words that mean "time." The first is most familiar—chronos . It means the chronology of days, governed by the carefully calculated earths' sweep around the sun. God himself ordained this measurement of days on the fourth day of Creation, spinning the heavenly lights "for seasons, and for days and years."
But another word for time is also used in the New Testament—kairos . This speaks more to specific, God-ordained times throughout history, sometimes called the "right time" or "appointed season" (Titus 1:3). Kairos is God's dimension—one not marked by the past, the present, or the future. When Jesus came, it was a fulfillment of promises past, a cosmic collision of the sacred and secular. It was an intersection of the holy will of God and the stubborn ways of man. It was a perfect moment. John the Baptist said in Mark 1:15 that "time is fulfilled, and the kingdom of God is at hand." !
This Godly kairos pierced its way into creation at just the right time, slicing through chronos with a cry of a baby in a manger
