We’ve all been there — watching a child lose themselves in an arcade, oblivious to the clock, convinced the fun will never end. They think they have all the time in the world. It’s easy to smile at that kind of innocence. But if we’re honest, don’t we live the same way?

That was the heart of a recent message drawn from Psalm 90, Isaiah 40, and several New Testament passages — a reminder that our days are numbered, and that recognizing that fact is the first step toward living wisely.

The Illusion of Unlimited Time

Kids have no real concept of time. A trip to the go-kart track or the arcade feels endless to them. One child at Rascals wanted to spend the whole hour on arcade games while his wristband — his ticket to the go-karts, bumper boats, and everything else — was ticking down. He had no idea the clock was working against him.

Sound familiar? We often live as though time doesn’t apply to us. We assume there will always be another day, another year, another opportunity. But Psalm 90 paints a very different picture.

Psalm 90: Our Days Are Fleeting

In Psalm 90:1–12, Moses writes:

“Lord, thou hast been our dwelling place in all generations. Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.”

He goes on to say that a thousand years in God’s sight is like yesterday — already past. Human life is compared to grass that flourishes in the morning and by evening is cut down and withers. That’s not a comfortable image, but it’s an honest one.

Then comes the key verse:

“So teach us to number our days, that we may apply our hearts unto wisdom.” (Psalm 90:12)

The logic is simple: if you don’t recognize that your time is limited, you’ll live carelessly. But if you number your days — if you acknowledge that they are passing — you’ll live with wisdom.

What’s in Your Dash?

You’ve probably seen it on a tombstone: a name, a birth date, a hyphen, and a death date. The hyphen represents an entire life. The question isn’t how long the dash is — it’s what you did with it.

Psalm 90:9 says, “We spend our years as a tale that is told.” What story is your life telling? Nobody wants the tale of their life to be, “Here lies a fool.” But without numbering our days, that’s the direction we drift — frivolous, distracted, and unwise with the time we’ve been given.

The Word That Endures

Isaiah 40:7–8 reinforces the same truth:

“The grass withereth, the flower fadeth: but the word of our God shall stand forever.”

We are like grass — here today, gone tomorrow. But God’s Word is eternal. If we’re going to seek wisdom, we won’t find it ultimately in our own experience or even in the advice of others. We’ll find it in the Word of God.

What Will Last?

Several New Testament passages drive this home:

• 1 John 2:17 — “The world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.”
• 1 Corinthians 15:58 — Your work in the Lord is not in vain. It’s not empty or pointless. It produces something worthwhile. Everything done outside of the Lord, however, amounts to nothing.

The implication is clear: if time is running out, we should invest it in the things that aren’t.

Today Is the Day

2 Corinthians 6:2 says, “Behold, now is the accepted time; behold, now is the day of salvation.”

First and foremost, if you haven’t put your faith and trust in Jesus Christ, today is the day. There’s no promise of tomorrow.

But even for those who already know Christ, today is the day of salvation in another sense — the salvation of your time. If you’ve been wasting it, today is the day to turn the page. Stop wasting time. Get busy for the Lord.
