What the Bible Says About Compound Interest

Fifty dollars. Twenty minutes.

That is how long I sat with my finger over the confirm button on my first real investment contribution, about five years ago, on an amount I could have replaced by skipping a few takeout dinners. I knew where the money was going. I went to school for financial services. I have held a mutual funds licence. And I still could not press the button.

Then I finally pressed it, and spent the next stretch of my life making the opposite mistake.

Both of those failures are sitting in the parable of the talents. Almost everybody who writes about that parable only notices one of them.

Two Ways to Waste the Same Ten Years

Matthew 25:14-30. A man goes abroad and leaves three servants holding his money: five talents, two, one. A talent was roughly twenty years of wages for a labourer, so this is not pocket change. The first two put it to work and double it. The third digs a hole.

The master comes back. The first two hear "Well done, good and faithful servant. You have been faithful over a little; I will set you over much" (Matthew 25:21, ESV). The third hears "You wicked and slothful servant" (25:26), and the talent is taken off him.

Now notice what usually gets skipped. Nobody stole the buried talent. There was no theft, no crash, no bad call, no market to blame. The servant explains himself, and his explanation is fear: "I knew you to be a hard man... so I was afraid, and I went and hid your talent in the ground" (25:24-25). He knew something was expected of him, and that knowledge became his reason to do nothing at all.

Now look at what the first two servants actually did, because it is less impressive than we remember it being. They put the money to work. Then the master was away a long time. Nothing in the story has them watching it.

That is the whole mechanism, and it is the reason this parable keeps showing up in conversations about investing. I have written at length about what the parable of the talents teaches about money and risk, so I will not re-run all of it here. The piece that matters today is the long absence in the middle of the story. Something had to be put to work, and then it had to be left alone while years went by.

There are two ways to fail that. You can refuse to start. You can start and then never leave it alone.

I have done both.

What Time Actually Does to a Dollar

Compound interest is growth on your growth. You invest, it earns a return, and then that return starts earning returns of its own. Nothing clever happens. It just keeps happening.

At a 7% average annual return, which is roughly what a diversified index fund has managed over long stretches of history, $1,000 turns into about $3,870 in twenty years. Leave it another twenty and it becomes about $15,000. Same dollar, same fund. The second half of the runway does almost four times the work of the first half.

The advice to start early stops being a platitude once you put numbers on it.

Two men, same salary, same discipline. The first puts $200 a month away from 22 until he retires at 65, and lands near $600,000. The second starts the identical habit at 32 and lands near $295,000. The gap is about $305,000, and the man who got there contributed only $24,000 more of his own money along the way. Ten years of $200. Everything else was time. If you want to see your own version of that curve, put your numbers through the compound interest calculator.

Ten years. That is what one delayed decision is worth.

The First Way to Waste It: You Never Press the Button

Nobody in my family talked about money when I was growing up. Not badly, not in crisis. It simply was not a subject. So by the time I had the schooling and the licence and an account open on my phone, I had a great deal of information and no instinct whatsoever, which turns out to be a worse combination than it sounds.

That is what the twenty minutes was. It was not confusion. I could have explained the mechanics of that contribution to a room.

Two things finally moved me, and neither one was a spreadsheet.

The first was seeing that investing did not have to be as risky as I had assumed. What I had been picturing was speculation, and that was never what I was buying.

The second was remembering something I had heard once: money sitting in a savings account is about as good as money under a mattress. That sounds harsh until you run the numbers. If your account pays you well under the rate that prices are rising, your purchasing power shrinks every year with total reliability. Statistics Canada put annual inflation at 3.0% in July 2026. A savings account paying half a percent charges you rent for the privilege.

That was the point where I knew I had to contribute and invest. Not because I had found courage. Because I had run out of reasons.

If you have felt that paralysis, you are in ordinary company, and you are not disqualified from starting today. But the feeling does not stop the clock. Every year you spend waiting for the version of yourself who feels ready is a year the compounding table above simply does not give you.

When I sit with people to talk about their stressors, more often than not money is part of it. And the paralysis almost never comes from ignorance. Underneath it is shame, and shame does not respond to information. A man who feels like his balance is a verdict on his character needs permission to start from exactly where he is, at the number he actually has.

If the fear runs deeper than the finances, if there is identity wrapped up in this for you, spend some time with what the gospel says about where your worth actually comes from. Anxiety has never built anything that lasted.

The Second Way to Waste It: You Press It Every Day

Here is the part I would rather not write.

Once I started, I went the other direction hard. This was the COVID years, when every week brought new channels teaching people how to invest and handing out their tip stocks. Safe ones, less safe ones. I tried them all. Big tech and Tesla, index funds, penny stocks, you name it. If the video made a convincing argument for me to buy it, I bought it.

I checked the account a dozen times a day. More, some days. Not to manage anything. Just hoping to see it go up.

I had some success early, which was the worst thing that could have happened, because it convinced me I was good at this. I stayed in too long. I sat there wondering whether to sell when it got low, knowing the whole time what I believed: you do not sell low, you wait it out, and better yet you do not take speculative bets to begin with. I knew it. I did it anyway. And I got burned.

That was not even the first tuition payment. In college I lost hundreds of dollars to MLM schemes and online courses promising passive income, years before I had a brokerage account to lose it in.

The honest version has two sides. Those same YouTube channels and Instagram accounts are also where I learned to actually apply personal finance. School gave me the mechanics. The internet taught me how to live them out. The problem was never that I was learning online. It was that I could not tell teaching from a tip.

It took me embarrassingly long to see the thing underneath both failures. The man with the hole in the ground and the man refreshing his portfolio are failing the same test. Neither one lets the years do anything. One buries the money so nothing can happen to it. The other keeps digging it up to look at it, which produces the same result and costs more in fees and nerves.

Time only pays the man who can stop touching it.

What the Master Was Actually Testing

The money you earn, and the years that money has to grow, are entrusted to you the way the master's property was entrusted to his servants. All of it belongs to God. You can use it. You can grow it. You will answer for what you did with it.

Most of us think of stewardship as a tithe conversation: what percentage goes to the church? That is part of it. Stewardship is wider. It covers what you do with the portion you keep, including whether you are building the capacity to be generous in twenty years, when the ask will be bigger than anything you can meet today.

Jesus describes a seed a man scatters before going to bed. It sprouts and grows while he sleeps, and he does not know how (Mark 4:26-29). The soil produces by itself. Then comes the harvest. The farmer's job in that story is to put the seed in the ground and then go on living.

Which is uncomfortable, if you are a man who likes to feel useful. There is no heroic version of this. You will not out-work compounding, and you cannot rescue it by paying closer attention.

Starting with $50 a month is real stewardship. It will not feel impressive. Fifty dollars a month from 22 lands about where $200 a month from 40 does, on less than half the money, and I know what fifty dollars feels like in your hand when you are about to send it somewhere you cannot see it.

Four Steps, and the First One Takes Ten Minutes

Step 1: Open a TFSA and check your contribution room.

A Tax-Free Savings Account is the best first investment account for most Canadians. The money grows tax-free and you pay no tax on the way out. The 2026 annual limit is $7,000, and unused room carries forward, so if you turned 18 in 2009 and have never contributed, your total room in 2026 could be as high as $109,000. Finding your exact number takes about two minutes in CRA My Account.

Step 2: Automate the contribution.

Do not decide each month whether to invest. Set it and forget it. Whatever you can manage, $50 or $100 or $200, make it move on payday. Money that sits in your chequing account gets spent. Money that leaves before you see it stays put.

Step 3: Buy one diversified, low-cost ETF.

You do not need to pick stocks. For most Canadians starting out, the simplest thing is an all-in-one ETF like Vanguard's VGRO or iShares XGRO, which hold thousands of companies across several countries in a single fund and rebalance themselves. A platform like Wealthsimple makes this straightforward: commission-free ETF trades, no minimum, and your balance on your phone. It is where my own accounts live.

Since I am the one telling you to keep this simple, you should know what is actually in my account. About 75% of my self-directed TFSA sits in broad index funds. The rest is individual names I picked myself, and the broad share went up after the burn I just described. If I were starting again tomorrow, I would make the 75% the whole thing.

Step 4: Leave it alone, and mean it.

This is the step I failed, so I will be blunt about it. Markets fall. VGRO finished 2022 down about 11%, and March 2020 was a genuinely frightening few weeks. Both recovered, the way every broad downturn in the history of diversified markets has recovered so far. Selling in fear locks in the loss and misses the recovery, and checking daily is just the slow approach to the same mistake. Delete the app off your home screen if you have to. I am not joking.

Common Questions

What does the Bible actually say about compound interest? Nothing directly, and anyone who says otherwise is selling something. But Matthew 25:14-30 turns on the idea: two servants put money to work across a long absence and are commended; the one who buries his out of fear is judged. Nothing was stolen. It never grew.

Should I pay off debt or invest first? Interest rate decides it. High-interest consumer debt, credit cards at 19% to 22%, comes first, because clearing it is a guaranteed return near 20%. Lower-rate debt is a judgment call: at 4% against a historical 7%, investing alongside the payments is defensible. That decision deserves more room than a paragraph, and it gets it in the full debt-or-invest walkthrough.

Is $50 a month really enough? Yes, and I say that as a man who took twenty minutes to send exactly that. The runway matters more than the number.

What if I am forty and starting now? Then you start now. The table still works, the numbers are just smaller, and the alternative is starting at forty-five.

Why the Twenty Minutes Still Bothers Me

This week: open CRA My Account and look up your TFSA room. Registering for CRA My Account takes a few minutes if you can verify your identity online; otherwise CRA mails you a security code first, which can take five to ten business days to arrive. Then open a TFSA, automate a contribution you will not miss, and buy one all-in-one fund.

That is the whole move.

Those twenty minutes still bother me, and the fifty dollars has nothing to do with it. I spent them being careful about the wrong thing, then spent a long stretch afterward being careless about the right one. The master in the story is gone a long while. That absence is the gift, and the men commended for it did the least interesting thing imaginable with what they held.

Put the seed in the ground. Then go and live your life while it grows.
