Revelation 3:5-8

5Everyone who wins against Satan will wear white clothes like they do. I will never remove their names from God's book of life. I will say clearly to my Father and his angels that those people belong to me.

6God's Spirit is speaking to you in the churches. You should understand what the Spirit is saying to you. You have ears, so listen carefully!” ’

7‘Write this to the angel of the church at Philadelphia: “This is my message to you. I am the one who is completely good, the true God. I have King David's key in my hand. When I open a door, nobody can shut it. And when I shut a door, nobody can open it.

8I know everything that you do. Look! I have opened a door that is in front of you. Nobody can shut that door. I know that you are not very strong. But you have obeyed what I told you. You have continued to believe in me.
