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.
We're the team behind Devotion Fund. We 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.
