Revelation 3:7-8

7 And to the angel (messenger) of the assembly (church) in Philadelphia write: These are the words of the Holy One, the True One, He Who has the key of David, Who opens and no one shall shut, Who shuts and no one shall open:

The Truth that brings us such great peace is that once Jesus does something it is done! That is why He chooses us and empowers us to choose Him. We do not first choose Jesus to be our Lord, He first chooses us to be His Bride! And when Jesus opens the door for us, it is never shut, Romans 11:29. 

Therefore I want you to understand that no one speaking under the power and influence of the [Holy] Spirit of God can [ever] say, Jesus be cursed! And no one can [really] say, Jesus is [my] Lord, except by and under the power and influence of the Holy Spirit. 1 Corinthians 12:3

And this is the will of Him Who sent Me, that I should not lose any of all that He has given Me, but that I should give new life and raise [them all] up at the last day. John 6:39

Amen the door for the truly saved is open and no one can shut it! Philadelphia is the only church that Jesus proclaims that He will keep. Look at how absolute Jesus sounds when He first addresses them. Jesus boldly proclaims the door is open and no one will shut it. This is how Jesus always is. Who He has chosen, He has called, He has empowered, He has sealed, He has glorified, and He will protect and keep. We are Jesus’ Bride and our Groom is more than committed to providing for us.  

8 I know your [record of] works and what you are doing. See! I have set before you a door wide open which no one is able to shut; I know that you have but little power, and yet you have kept My Word and guarded My message and have not renounced or denied My name. 

Once again, Jesus has opened the door for us and no one can shut it, including ourselves! Jesus will Shepherd us through that door and because of Him we will always be more than conquerors! 

For the Church of Philadelphia to keep God’s Word and to guard the message, it has had to be Jesus within them empowering them to keep it. The Holy Spirit is their strength and He is their seal! It seems they have just a little power; the world with all of its evil keeps on going: war, sin, false religion, but even with all of these things going on they cannot loose their Head, which is Jesus. They cannot leave the Vine. They cannot leave the fold. They can’t because they are dead and nevertheless they live, yet it is not them who lives, it is Jesus in them Who lives.
