You can knock on the largest door in the world, but it will take 45 minutes to open. The Vehicle Assembly Building (VAB) at the Kennedy Space Center is huge! How huge is it? It is 220 feet higher than the Statute of Liberty. Its volume capacity is 52 million cubic feet more than the Pentagon. Its doors are the largest in the world, measuring 456 feet high (think 35 story building).
The VAB's doors were made to accommodate the Apollo Program's Saturn 5 rockets. These days they are the entryway for the entire Space Shuttle.
The 2011 copy of Guinness World Records will tell you this is the largest door in the world. I think there is one that is bigger.
In Revelation 3, Jesus addresses the church at Philadelphia. Located at a geographical crossroad, Philadelphia was on a main route for the imperial postal service, Caesar’s armies, and traveling merchants. No wonder they called it the “Gateway to the East.” To God it was an interstate highway on which the message of the gospel could travel. Apparently, the church of Philadelphia would play a crucial role in spreading that message. For a little church, such a big assignment could be intimidating so God took the time to teach them the lesson of the open door.
To the angel of the church in Philadelphia write: These are the words of him who is holy and true, who holds the key of David. What he opens no one can shut, and what he shuts no one can open. I know your deeds. See, I have placed before you an open door that no one can shut. I know that you have little strength, yet you have kept my word and have not denied my name. (Revelation 3:7-8 NIV)
A quick review of Scripture tells us that God opens doors to share the message of Jesus with other people (2 Corinthians 2:12; Colossians 4:3; Acts 14:27). The exclamation point to that lesson is found in Revelation 3. The door God opens is the door God blesses. If God gives you an opportunity (an open door) to share Christ, would he slam it in your face the minute you venture through it? Of course not. God doesn’t waste time. If he “goes to the trouble” of opening a door, it is for one reason only—so that you may walk through it and share the only message that can lead people to true life. Look for God's open door. When you see it, there is only one thing to do—walk through it!
MY PRAYER: Lord, open a door to share Jesus where I live and work. Make it so big there is no way I can miss it.
