I gave them away, one at a time
This will sound weird, but I got a pack of these before taking off on a 5-week hike. I reviewed the cards frequently and made a point to give away each card as I met people along my journey who embodied each word. I don't know whether each recipient was a believer or not, but universally the cards were well-received. The people I gave them to appreciated the recognition and it was a good reminder to me to always be on the lookout for God's goodness in the world around me.
