'Open' in the Bible

"To the messenger of the church in Philadelphia, write: "The one who is holy, who is true, who has the key of David, who opens a door that no one can shut, and who shuts a door that no one can open, "says this:

"I know what you've been doing. Look! I have put in front of you an open door that no one can shut. You have only a little strength, but you have obeyed my word and have not denied my name.

After these things, I saw a door standing open in heaven. The first voice that I had heard speaking to me like a trumpet said, "Come up here, and I will show you what must happen after this."

I also saw a powerful angel proclaiming with a loud voice, "Who is worthy to open the scroll and break its seals?"

No one in heaven, on earth, or under the earth could open the scroll or look inside it.

I began to cry bitterly because no one was found worthy to open the scroll or look inside it.

"Stop crying," one of the elders told me. "Look! The Lion from the tribe of Judah, the Root of David, has conquered. He can open the scroll and its seven seals."

They sang a new song: "You are worthy to take the scroll and open its seals, because you were slaughtered. With your blood you purchased people for God from every tribe, language, people, and nation.

Then I saw the lamb open the first of the seven seals. I heard one of the four living creatures say with a voice like thunder, "Go!"

Then I saw the lamb open the sixth seal. There was a powerful earthquake. The sun turned as black as sackcloth made of hair, and the full moon turned as red as blood.

After these things, I looked, and the Temple, which is the Tent of Testimony in heaven, was open!

Then I saw heaven standing open, and there was a white horse! Its rider is named Faithful and True. He administers justice and wages war righteously.

I saw the dead, both unimportant and important, standing in front of the throne, and books were open. Another book was opened the Book of Life. The dead were judged according to their actions, as recorded in the books.
