A World Kindness Day Family Challenge
Today is World Kindness Day, and I want to invite you to celebrate with a fun family challenge that combines a little mystery, a little adventure, and a whole lot of love!
The mission? To sneak around doing good deeds, spreading smiles, and leaving little surprises of kindness, all without getting caught! In other words, become a Secret Kindness Ninja!
Here’s how it works:
Step 1: Gather your ninjas.
Call a quick family meeting and announce the challenge! Explain that, for the next 24 hours (or whatever your predetermined amount of time is), everyone in the family is going to become a Secret Kindness Ninja with the mission to look for opportunities to make someone else’s life a little easier, happier, or brighter. Just like ninjas are secretive and mysterious, part of this mission is to do it secretly!
Step 2: Prepare your ninja supplies.
Every good ninja needs a few supplies! Print off some of our “You’ve been ninjaed” card, and include those with a small supply of craft items like paper, markers and stickers, as well as small treats/ inexpensive surprises. Note: You don’t need to spend any money to participate. Some of the very best acts of kindness are completely free!
Step 3: Choose your secret missions.
Now the fun begins! Throughout the day, everyone should look for opportunities to secretly bless another person with a small act of kindness. Here are a few ideas to get you started:
Secret Kindness Missions at Home
- Make someone’s bed when they aren’t looking.
- Secretly complete a chore that belongs to someone else.
- Leave a sweet note on a sibling’s pillow.
- Make a family member’s favorite snack.
- Tidy up a shared space without being asked.
- Leave a drawing or encouraging message for someone to discover.
- Set the table or clean up after dinner without being asked.
- Share a favorite toy or item with a family member.
- Play a sibling’s favorite game with them.
Secret Kindness Missions Beyond Your Home
- Leave a thank-you note for your mail carrier.
- Deliver a little surprise to a neighbor’s doorstep.
- Write an encouraging card to a teacher or pastor or coach.
- Return a neighbor’s trash bins to their usual spot.
- Leave a note of encouragement for a friend.
- Bring a small treat to someone who has been working hard.
- Write a thank-you card for a community helper.
- Secretly help prepare a meal or care package for someone who could use encouragement.
Remember, the goal isn’t to do something big or expensive. The goal is to notice people and look for ways to love them well.
Step 4: Leave Your Secret Ninja Calling Card!
Here’s where the mystery gets even more fun. After completing a secret act of kindness, leave behind a little card that says: YOU’VE BEEN NINJAED!
You can even invite them to become a Kindness Ninja themselves and pass the kindness along!
Imagine how much joy could spread if one small act of kindness inspired another, and another, and another.A little kindness can travel a long way!
Step 5: Gather for a Family Ninja Debrief
At the end of the allotted time, gather together and talk about your adventures.
You can share some of the missions you completed, or keep them secret a little longer!
Ask each other:
- What was your favorite act of kindness today?
- Was it difficult to do something kind without getting credit?
- Did you notice opportunities to help that you might normally have missed?
- How did doing something kind make you feel?
- What are some ways we could keep being Kindness Ninjas all year long?
And here’s one more question worth discussing:
What would our home feel like if everyone was always looking for little ways to make life better for someone else?
The Beautiful Thing About Secret Kindness
There’s something especially wonderful about kindness that doesn’t need recognition. When we do something good without expecting anything in return, we’re practicing a special kind of love.
We’re learning to notice the needs of others, to take initiative, and to find joy in giving. And we’re reminding ourselves that kindness isn’t just something we do when it’s convenient or when someone is watching. It’s a way of living.
The Bible reminds us: “Be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you.” (Ephesians 4:32) Paul doesn’t ask us to be kind because people deserve it. He points us back to how God has treated us. We are kind because God was kind first.
Here’s a fun detail from the Greek. The word for kind is chrēstos and it sounds a lot like Christos, Christ. Some early Christian writers noticed the similarity; outsiders sometimes even mixed the two words up. This doesn’t feel like an accident. Instead, it seems like a beautiful reminder that the people of Christ should be known as the kind ones. Not just because of a similarity of words, but because of how we live.
We don’t have to wait until we’re older, have more money, or have more time to make a difference. We can start right where we are, with the people around us, using whatever we have in our hands. The kindness of God has changed our lives, so let’s use every opportunity to show kindness to others, too!
The Kindness Ninja Code
Read this with your kids. If you’d like, have everyone raise their right hands, and take the oath (dramatic music optional):
- A ninja works in secret. No bragging, no hints, no “Guess what I did?”
- A ninja is kind to everyone, especially the people who are hard to be kind to.
- A ninja leaves no mess, only a little card that says, “You’ve been ninja’d!”
- A ninja is safe. Missions outside the home happen with a grown-up.
- A ninja does it with joy. Kindness with a grumpy face doesn’t count.
Then pray together, “God, You have been so kind to us. Thank You for sending Jesus, Your loving kindness with a face. Make our family kind, tenderhearted, and forgiving. Help us notice what others need and serve them quietly, with joy, for You. Amen. Ready, Set, Ninja!”
Happy World Kindness Day!
P.S. You don’t have to stop after today! Make Secret Kindness Ninjas a monthly family tradition, a birthday surprise, or a special activity whenever your home could use an extra dose of love.
