You've already got enough photographs for a show.I would pick through those and put something together.
As an additional step, you could collaborate with someone(s) in your church to match the images with inspirational texts: poetry, holy writ, etc. Display the texts next to the pictures on the cards. Then you have the option of selling prints. Or correspondence cards with the images and texts printed on one side with the reverse blank for the message. I'm envisioning something slightly larger than a postcard, but one-sided, non-folding, with envelope. (I suspect printing might be cheaper this way. But you would have to investigate and find out.)
Photos!

Just a thought.
