When we know who we are in Christ and we know what HE has called us to do we then learn to walk in the authority The Lord has given us.. We have died to flesh and we have been purified through the fire . Let no man close the door the Lord has opened for you to walk through.. If doubt sets in then take the time to remember all the years and times the Lord has confirmed HIMSELF to you. The enemy will come to steal, kill and destroy, but the promise in Matthew 16 holds true for us that have learned the inner workings of Kingdom Government and authority.--
Also in Revelation 3 it shows Christ has the key of David and can open the doors and no man can shut it...
It tells us in Matthew 16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
The Keys to the kingdom are given to those that are on solid rock, the true church of Christ --The key of David is given to Christ----Isaiah 22:22 And the key of the house of David will I lay upon his shoulder; so he shall open, and none shall shut; and he shall shut, and none shall open.
Revelation 3:7 And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;8 I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name.
