15,409 Days: Psalm 90 and Wisdom

15,409 days. That’s how long my dear wife lived on this Earth. When we were dating, we obviously had no idea. When we got engaged, there were no mystical revelation. And when we got married, this number certainly wasn’t written on the back of the marriage certificate for us to see.

In our twenties we were rather unaware. Most of our thirties passed normally. But cancer struck when she was 38 and death was suddenly part of our thoughts about the future. She would end up living four more years. Chemotherapy would work excellent and she would carry on. But one year ago the unwelcome guest would visit again. This time cancer never left. My wife lived 15,409 days. How would we have lived differently if we had a ticker counting down each day. What if we knew when we got married that she only had 8,174 days left? What would we do differently? Or when our first child was born, would knowing she only had 3,577 days left have changed the myriad of decisions we would make as we raised our children?

Some would object to this way of thinking. With all the swagger of Wayne and Garth, they would cry “live in the now!” Why waste time worrying, just live! Live your life “authentically” as you go from day to day. But another voice would disagree. With, perhaps, his staff in hand and maybe a veil on his face, he would say the opposite. “Teach us to number our days, oh Lord, that we might get a heart of wisdom.”

Psalm 90

In Psalm 90 Moses declares four characteristics of God and what our response should be. In verses 1-2 he speaks of the eternality of God. God has always been. He was before all things, and He will be after all things. And always has He cared for His people. In verses 3-6 he writes of the sovereignty of God. God controls the timing of death (3, 5) and does so with ease (6). Indeed, even time is not a factor for Him (5). In verses 7-11 Moses declares the holiness of God, highlighting our own sinfulness (8) and His just and righteous wrath (7, 9). He contrasts the strength of God’s wrath (11) with our own weakness (10) thus glorifying His omnipotence.

It is following this striking description of the character of God, one that includes the severity and seriousness of His holiness, that the Psalmist admonishes us to “number our days.” God’s eternality is contrasted with our own vapid brevity. While God is eternally His people’s dwelling place (1), we must reckon afresh with our sin and scant number of days on this earth.

The psalmist is not poking us to make fun or shame us. Rather, he knows that if we see our slight frame compared to the immeasurable weight of God’s character, we will see life from the correct perspective. The fleeting pleasures of sin (cf. Hebrews 11:24-25) will be nothing in comparison to the eternal weight of glory which God works in His child (2 Corinthians 4:17-18). In a very real way, counting up your days will lead you to live more wisely, if you humbly receive the truth of your smallness in light of God’s love.

But he does not leave us in this mean estate. No, he now tells of the favor of God, which He bestows upon those who learn this heart of wisdom and follow the Lord. In verses 13ff he describes the request of God’s people that God would care for them. For if God’s favor rest upon you, blessed indeed you will be.

So the question we much each answer is this: will we listen to the voice that tells us to exist solely for the present moment and the pleasures of this life, or will we listen to the voice with a staff in his hand and a veil on his face? The voice that would have spent time with God–face to face–as a friend? The voice that says to use your time wisely since you don’t know how much you have. One of these voices is well acquainted with the character of the Lord. This voice knows that eternity is coming and that our present life is as fleeting as a vapor. That the next life will last forever.

Which voice are you listening to right now?
