Jesus came in the fullness of time.  He will come again in the fullness of time.  Wherever Jesus, the Christ, is the time is brought to its fullness.

We often experience our time as empty.  We hope that tomorrow, next week, next month or next year the real things will happen. But sometimes we experience the fullness of time.  That is when it seems that time stands still, that past, present, and future become one; that everything is present where we are; and that God, we, and all that is have come together in total unity.   This is the experience of God's time.  "When the completion of the time came [that is: in the fullness of time], God sent his Son, born of a woman" (Galatians 4:4), and in the fullness of time God will "bring everything together under Christ, as head, everything in the heavens and everything on earth" (Ephesians 1:10).   It is in the fullness of time that we meet God.
