I have given you the keys to the Kingdom. What are keys for? They are meant to open things that have been locked up or lock things that are to be kept safe. Who are keys given to? Those that can be entrusted with the authority and responsibility of valued possessions.
Just like I handed Peter the keys to the Kingdom, so I give you the keys to the Kingdom. I give the keys to those that can be trusted with the secrets and mysteries of the Kingdom, who understand their authority because of the blood of My Son.
For it is time to unlock the secrets and mysteries of the ages, to bring forth the manifestation of the sons and daughters of the Kingdom of Light. For My Kingdom is accelerating and advancing, overtaking the darkness. Therefore, take the keys and release light and life, hope and peace. Go forth in power and authority, and destroy the works of the enemy.
Matthew 16:19 Amplified Bible (AMP)
I will give you the keys (authority) of the kingdom of heaven; and whatever you bind [forbid, declare to be improper and unlawful] on earth will have [already] been bound in heaven, and whatever you loose [permit, declare lawful] on earth will have [already] been loosed in heaven.
Isaiah 22:22 Amplified Bible (AMP)
Then I will set on his shoulder the key of the house of David;
When he opens no one will shut,
When he shuts no one will open.
Revelation 3:7-8 Amplified Bible (AMP)
7 “And to the angel (divine messenger) of the church in Philadelphia write:
“These are the words of the Holy One, the True One, He who has the key [to the house] of David, He who opens and no one will [be able to] shut, and He who shuts and no one opens:
8 ‘I know your deeds. See, I have set before you an open door which no one is able to shut, for you have a little power, and have kept My word, and have not renounced or denied My name.
