The word sounds old. Maybe even a little intimidating.
But here is what a tithe actually is: ten percent of your income, given to God.
That's really all it is. One tenth, given first, before you figure out what the rest of the month holds.
Where the Idea Comes From
The tithe is not a church invention. It goes back thousands of years in Scripture. In the Old Testament, God asked his people to bring the first tenth of what they earned or harvested. The word "firstfruits" appears throughout those passages. It means the first portion of what came in, given before anything else, not whatever happened to be left at the end. The ordering carries the whole weight of it.
Proverbs 3:9 says it plainly: "Honour the LORD with your wealth and with the firstfruits of all your produce." You give before you know how the rest of the month goes. Giving in that order turns it into an act of trust rather than a line in a budget.
In the New Testament, Jesus does not cancel the tithe. In Matthew 23:23, he actually affirms it. But he pushes further. The Pharisees were careful to give exactly ten percent of their herb gardens while ignoring justice and mercy. Jesus said they should have done both. The number is real, and it still matters, but it was never meant to be where the whole thing stops. What tithing is really doing is shaping the heart of the person who practices it.
How the Number Works
Ten percent of what, exactly?
For most teens, the math is simple. If you earned $300 babysitting last month, your tithe is $30. If your paycheque shows $420 after deductions, give from that.
There is a grown-up debate about gross versus net tithing. Gross is what you earned before taxes. Net is what actually hits your account after Canada Revenue Agency takes its share. For someone with a complicated income situation, that distinction matters. For a teenager with a part-time job, it does not. Give on what you received. Start somewhere.
The teen who gives $25 a month consistently will develop a habit the teen who debates the math never will.
Do not let a math question become a reason to keep waiting.
How to Actually Do It
Here is the practical side.
First, decide where your tithe goes. The natural starting point is your home church. That is where you are spiritually fed, where the gospel is preached, where community actually happens. Nobody is forcing you to start there. It just makes good sense.
Second, set it up so it happens automatically. Many Canadian churches have online giving platforms, and most let you schedule a recurring monthly gift. Once the schedule is set, giving stops being a weekly decision you might talk yourself out of.
Third, give before you spend. This is the "firstfruits" idea made practical. If your plan is to give whatever is left after everything else, it will almost never happen. The sequence that works: paycheque lands, ten percent goes out. In that order.
If your money arrives on a specific day, set a calendar reminder or an automatic transfer for that same day. Ten percent, sent before you decide what to do with the rest.
What If You Don't Have Much?
This is the honest question.
You are 16 and making minimum wage. You are trying to save for a car or put something toward school. Does giving ten percent actually make sense right now?
The honest answer is yes, and here is why.
The habit you build in your teens is the habit you carry into your twenties, your thirties, and beyond. If you wait until you feel financially comfortable before starting to give, that day tends to keep moving forward. There will always be something else the money could do.
Giving $20 a month when you earn $200 a month teaches you something that giving $200 a month when you earn $2,000 does not. It trains your hands to stay open. It puts you in the habit of trusting God with what comes next, instead of assuming you know better than him how to spend it.
Consider what it would mean to arrive at your first full-time job already in the habit of giving, already treating it as a non-negotiable. Most adults spend years trying to build that rhythm, and you'd have a head start on all of them.
The dollar amount will grow on its own as you earn more. What you're actually building right now is the habit underneath it.
What the Tithe Is Really For
Tithing can become mechanical. Write the transfer, check the box, move on.
If that's all it ever is for you, you've missed most of it.
The heart of tithing is recognizing that everything you have came from somewhere outside yourself. Your ability to earn money, the job that showed up, the health to work it. God's fingerprints are on all of it. The tithe is a regular, deliberate way of saying: I know where this came from, and I am holding it loosely.
When you give before you spend, you are making a declaration. You are saying that you trust God with what comes next, that you believe he is good and will provide, and that money is a tool you use rather than a master you serve.
2 Corinthians 9:7 is worth sitting with: "God loves a cheerful giver." Cheerful is the word that matters there, rather than reluctant or guilt-driven. The goal is to get to a place where giving genuinely feels like freedom. That takes time and practice. It also has to start somewhere.
Generosity is one of the most consistently life-giving things you will ever do. Every time you give, it draws you a little closer to God, because God himself is the generous one. When you give, you are reflecting something of who he is.
Your Next Step
If you have any income right now, here is what to do this week.
Write down what you earned last month. Calculate ten percent. Look up your church's online giving page, or ask someone how to set it up. Make one gift this week, even a small one.
Then, if you can, schedule a recurring monthly gift so it happens without a decision every month.
One action. One habit started. The theology deepens as you go. The practice begins now.
