Ps.90:12 – So teach us to number our days, that we may gain a heart of wisdom.
This Psalm is a Psalm of Moses. In this Psalm Moses reflects on the eternal nature of God and the fleeting moments of our mortal lives. For the Lord, time is meaningless, He actually is unaffected by time seeing He created time. For Him, one day is like a thousand years and a thousand years is like a day. Moses watched an entire generation, over 2 million people, die in the wilderness during a forty year period. He was deeply effected by the fragile, brief life we all cling to in comparison to the Eternal One who exists forever. Here is how Charles Spurgeon sees this passage.
“For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night.” Yesterday, while it was with us, was a short period of twenty-four hours. But when it is past, it seems like nothing at all. A thousand years, all big with events that we consider to be full of weight and importance, make up a long period in which myriads of men come and go. Yet those thousand years in God’s sight “are but as yesterday when it is past,” or but as the few hours in the night during which the sailor keeps watch at sea and then is relieved by another. A thousand years are like a watch in the night to the Eternal, and he needs no one to relieve him, for “he that keepeth Israel shall neither slumber nor sleep”
We have seen how fragile and brief life can be in this last year. Far too many people have died as we have all been stunned by the weirdness of the corona virus. One day it seems like just another cold or a flu, the next day somebody dies. This dying is what brings us face to face with our own mortality and the nearness of our eternal state. Moses said to number our days. Maybe you know the number of your life savings or checking account. Maybe you know the number of your paycheck that you will get this week. But have you thought to number your days? Of course you can’t know exactly how many days you have left in this life, we just need to value the ones that we have left and use them for God’s glory.
