He made the moon to mark the seasons; the sun knows its time for setting. You make darkness, it is night, when all the beasts of the forest creep about.

   - Psalm 104.19, 20

The substance of those things, which are made by Him, began in Him before all the ages of the world, not in time but with times. Time, indeed, is made with all things that are made. It is neither made before them, nor is it preferable to them, but it is co-created with them.

   - Eriugena, Homily on John 1.1-14, Irish, 9th century

What is time? In one sense time is merely the succession of moments flowing out of the future, through the present, into the past. 

But, in another sense, time is only the present moment. The past is gone and remains in memory only. The future is merely prospect; it does not yet exist, except in the mind of God. The only time we have is the present moment, and even the present moment of time is not our own, but the Lord’s.

For He created everything into time, and time with everything as the context in which everything exists. In that case, the cliché ways we refer to time tell us as much about our relationship with the Maker and Sustainer of time as with time itself: “wasting time,” “good times,” “hard times,” “the time of my life,” and so forth. We know something about what such phrases mean with relationship to time, but what do they suggest about how we regard the one in Whose hands all time rests?

It is significant that, in Ephesians 5.15-17, Paul did not say, “Make the most of your time” but “Make the most of the times.” Time exists above, around, beneath, and through us all, and it is kept in place only by the will of Him Who, day by day, brings the light and makes the darkness. Time is not ours, not really. Time is from the Lord and belongs to Him. Each moment of time is sustained by the Word of the Lord, Who upholds all things by His power (Col. 1.17; Heb. 1.3). The time you are taking to read these words is not your own; it belongs to Him Who makes and sustains it every moment of every day. So, whether we “waste” the time or “make the most of it,” we are saying something about our regard for the Creator and Sustainer of time, and that at every moment, in every situation, no matter what we’re doing in the time allotted to us.

What will the moments of time that mark the passage of this day say about your love for the One Who opens His hands and gives you the gift of time, moment by moment, day by day?

Psalm 90.12-15 (Landas: “My Faith Has Found a Resting Place)
So teach us all our days to note that wisdom may be ours.
Return, O Lord, have mercy on those servants who are Yours.
Each morning let Your love appear that we for joy may sing.
And make us glad for every day You us affliction bring.
