His past... Our past... What now?

PSALM 90

Lord, you have been our dwelling place[a]
    in all generations.
2 Before the mountains were brought forth,
    or ever you had formed the earth and the world,
    from everlasting to everlasting you are God.

3 You return man to dust
    and say, “Return, O children of man!”[b]
4 For a thousand years in your sight
    are but as yesterday when it is past,
    or as a watch in the night.

5 You sweep them away as with a flood; they are like a dream,
    like grass that is renewed in the morning:
6 in the morning it flourishes and is renewed;
    in the evening it fades and withers.

7 For we are brought to an end by your anger;
    by your wrath we are dismayed.
8 You have set our iniquities before you,
    our secret sins in the light of your presence.

9 For all our days pass away under your wrath;
    we bring our years to an end like a sigh.
10 The years of our life are seventy,
    or even by reason of strength eighty;
yet their span[c] is but toil and trouble;
    they are soon gone, and we fly away.
11 Who considers the power of your anger,
    and your wrath according to the fear of you?

12 So teach us to number our days    that we may get a heart of wisdom.

Moses is looking back on his life, and the life of his nation.  He has watched a generation or two die in the wilderness due to their sins.  He can look back on his long life with extra days and see lots of failures. But then he looks back beyond that and He sees Eternal God, watching over it all - above the mountains, in the cloud over the wilderness caravan, in the thick of every challenge.  He is not able to see how small, sinful and short of span man is before God.  What should that cause us to do? Come in confession and get perspective about what really matters. See life as a special gift and seek His wisdom as to how to use it.  Sounds like an agenda for the day, and more.
