I noticed this key in the cupboard door when I was looking for old treasures to photograph. Funny thing about these keys, it doesn't matter what cupboard they come from they undo the locks in the all other other cupboards ... so these old keys are really used to latch the doors rather than lock them.
Revelation 1:18 (New International Version)
I am the Living One; I was dead, and behold I am alive for ever and ever! And I hold the keys of death and Hades.
