The thumb alone would convince me
In the absence of other proof, the thumb alone would convince me of God's existence.
When I am dead, come to me at my grave, and the more often, the better. Whatever is on your soul, whatever may have happened to you, come to me as when I was alive and, kneeling on the ground, cast all your bitterness upon my grave. Tell me everything and I shall listen to you, and all the bitterness will fly away from you. And as you spoke to me when I was alive, do so now. For I am living, and I shall be forever.
