A support letter gets read once and often filed away. A newsletter gets skimmed and forgotten by next month. A prayer card, if it's good, sits on a refrigerator, in a Bible, or on a desk for a year — which makes it one of the highest-leverage, lowest-effort pieces of support-raising material a missionary can make, and one of the most commonly done badly.
Keep it to what fits on a card someone glances at for five seconds, not a mini support letter:
That's it. If you're also including a full paragraph of testimony, a Bible verse, a family history, and a detailed ministry description, the card has become a flyer no one finishes reading. Save the fuller story for your support letter or your fundraising page bio — the prayer card's only job is to be remembered.
"Pray for our ministry" and "pray for the lost" are true, sincere, and completely unmemorable — a reader has nothing concrete to hold onto, so nothing happens after they read it. Compare that to points like these:
Specific points do two things generic ones don't: they're easy to actually remember and pray for on a random Tuesday, and they quietly demonstrate that your ministry is real and current, not a vague line item. Rotate your two or three points as circumstances change, rather than trying to cover everything at once.
You don't have to choose — most missionaries end up using both, for different moments:
A prayer card that only asks for prayer misses the person standing right there who was already planning to give something before they read it — they just need the path to be short. A QR code that opens your Devotion Fund page directly, or a link simple enough to type from memory later, removes the single biggest source of drop-off between "I want to support this" and an actual first gift. Pair the ask with the prayer points instead of treating them as separate requests; most people who pray for you regularly are also the people most likely to give.
Set a recurring reminder to review your prayer card every 6-12 months, and update it immediately after anything major — a new assignment, a finished language-learning milestone, a new child, a role change. An old photo or a prayer point that resolved a year ago tells a supporter, even subtly, that they haven't heard from you in a while. Refreshing the card is also a natural moment to send it along with your next newsletter update, so it reaches your existing supporters, not just new contacts.
What size should a missionary prayer card be?
Standard business card size (3.5" x 2") is cheapest and most common; a postcard size (4" x 6") gives more room for a photo and doubles as a mailer.
How many prayer points should a prayer card include?
Two or three, and specific enough that someone can actually remember and pray them — not a general "pray for our ministry."
Should a prayer card include a way to give?
Yes — a QR code or short link to your support page, alongside the prayer points, so someone ready to give has an immediate next step.
How often should I update my prayer card?
Every 6-12 months, or right after any major change, so the photo and prayer points stay current.
I'm Jussi, the founder of Devotion Fund. I wrote this after noticing how many missionaries pour hours into their support letter and newsletter but treat the prayer card as an afterthought — even though it's often the single piece of paper that outlasts everything else you hand someone.
