Summary: This is a study of the church of Philadelphia in the book of Revelation. This is a controversial subject but takes a conservative approach to understanding the book.
Note: I used many sources to study this book, one of my favorites is Revelation: God’s Word for the Biblically-Inept by Daymond Duck and some out of different study bibles.
Title: Revelation: The church of Philadelphia
Ephesus-Apostolic Age to 100 AD Church of the departed love
Smyrna-Martyrdom Age 100 to 314 AD Church of fiery persecution
Pergamos-World Alliance 314 to 590 AD Church of world alliance

Sardis- 1517-1800 AD Church of the Spiritually Dead
7. And to the angel (messenger) 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;
Characteristics of Jesus
1. he that is holy
2. he that is true
John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
3. he that hath the key of David
Eliakim was the key holder to David’s palace. He had the rights to all rooms and what he opened stay open and what he close stayed closed by the authority of the king. Is 22:20-25
David was the ultimate king. As being the king of Israel and Israel being God's chosen nation the David could be king of all. Jesus is the ruler of all.
a. he that openeth and no man shutteth
b. and shutteth and no man openeth
Matthew 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. 19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, [even] unto the end of the world. Amen.
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.
1. I know thy works
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God: 9 Not of works, lest any man should boast. 10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
2. behold, I have set before thee an open door, and no man can shut it
What could this open door be? Maybe an open door to understanding his word. Maybe an open door to witnessing. Maybe an open door of opportunity to work for the Lord. What could it be?
Russia tried to close the door to the church but during the time the church grew and the doors were reopened. China is trying to close the door to the church but again the church is growing, underground, and I believe that one day that door will have to open.
3. For thou hast little strength (power)
Jesus loves people like this. Maybe small. May seem to be weak but they are strong in the Lord.
4. And has kept my word.
Here is the most important phrase of all. What were they known for? Keeping the word of God. Holding fast to its inspiration and obeying its commands.
