Hiding Bibles for the Tribulation saints?

I volunteer in my church's ministry. It has a thrift store front. The building, which looks like a triple wide, serves the homeless, women, and we also host a Spanish church and pastor in the same building.

I post items for sale on social media. That's my big contribution. Proceeds support these ministries.

A few weeks ago, two men came in. They were elderly. One man said he wanted to give us Bibles. The store wasn't in need of Bibles so they said thanks, but no thanks. I felt bad so I chatted a bit with them. I asked if I could pray for them. As they left, they handed me their card so I had their name.

The Gideons International.

I tucked the card in my pocket and continued on.

This past week, I have had an idea ruminating in my brain. I want to hide Bibles all over the Valley. I want to do this for the Saints - our family. I hope that the Spirit will guide them to these places. I was looking to buy Bibles online as taking them from stores will reduce their availability right now. Last night I ordered MacArthur's 2nd Edition Study Bible as a treat for my family. I started going through tracts, thinking I could combine them with the Bibles. Then this morning I woke up and thought about including the Left Behind letter.

Then I found the card from the Gideons on my keyboard.

So does this sound mental? My 19YO said he would help. I am sure his friends will also help. 

Before I start I am looking for things that I haven't considered. This feels like it would be all consuming and I don't want to be rash about it.
