I love how many times the white stone is mentioned in the bible and its significance! It has led me to pick up small white stones all through my life and even use them for ministry. Twenty years ago, I gave a white stone to an alcoholic with this verse written on an index card. He checked himself into rehab and has been sober ever since. Do I have special healing powers? No, probably not. But God can use anyone as his instrument and perhaps he worked through me to help one of his children.... Rev1 2:17
"He who has an ear, let him hear what the Spirit says to the churches. To him who conquers I will give some of the hidden manna (food) and I will give him a white stone, with a new name written on the stone which no one knows except him who receives it."
We have little white round stones all over the house and carry them in our pockets at times. I find many on the beach and can never pass by one without picking one up. It is like finding a gift from God that tells me he is there.
