In the 3rd chapter of Revelation, verse 8, the Lord Jesus has promised an ' open ' door of exaltation and blessings to the believers in the Philadelphian church of Asia. Why does he promise it ? Because he favors their spiritual condition. What is their condition ? They have a little strength, they've kept his word, and they have not denied his name. How does he have the power, or authority to open this special door ? Because of who he is ( vs. 7 ). He is holy, he is true, he holds the key of David, and he has the power to open and shut all doors, and no man can undo what he has done. Not all of the congregants are pleasing to his sight. The true followers are in the midst of false believers that are of the synagogue of Satan. The true believers must hold on to their true faith and word of patience to get to the open door that's only promised, it hasn't been manifested yet. They, like any local assembly of today must learn how to cope with the presence of tares. They will be tempted to approach other doors that he didn't promise in the journey towards the ' open door '. As a believer, the enemy will try and deceive you by allowing you to open another door, or he may open it for you. But, Jesus said the door that he promised would already be open at your arrival. He said he would set it as an ' open door '.
