Keys - Secrets

This key system caused me to do a bit of biblical thinking

Here is a key I have never seen before. It appears to me that it is a form of skeleton key but because it has another key to take it out of the lock or use the big flat part once it is in the lock. I guess you could say that it is two keys in one. When the smaller key is inserted into the big flat part, it unlocks the very small nib at the left hand end of this photo and that part then is able to turn and line up with the big flat part. Once this is accomplished, the entire key can then be turned in the lock to lock or unlock the door. Further, the big flat part cannot be inserted or taken out of the lock without that smaller key, rather ingenious.
Gods Word, the bible, is like that, it is only a history book full of names and dates and events until one is born again (John 3:3) then it becomes a His Story book full of secrets that He then unlocks in the mind of that born again believer. That, however is the 1st key that allows one to See through the glass into His Kingdom. The 2nd part of the mystery is getting the key that lets you enter His kingdom, it is a two key system, rather ingenious.
