If you have ever watched in of the  Harry Potter serious or heard of it you know that it was a fictional character, where he flew and had powers and always seemly was on the side or right at the end of the day Harry always ended up being the hero, however none of this was real simply entertainment  for the eyes.  Christ saw the church of Sardis that way, they seemly to anyone looking from the outside to be a church of heroes and on the right side, to be a church filled with the fire of the Lord but in fact their flame had gone out. Perhaps the church lost its focus and forgot that it must be God centered.  The church of Sardis was known far and wide.  Today it would be a mega church,   there was no shortage of money, talent, or manpower. Outwardly, it had every indication of a church on fire for the Lord. Christ revealed those things that were hidden were now brought to the light for the world to see. Pastors often determine how  successful their ministry and their church  is its membership and the building size and how much money is in the collection plate. The way we evaluate successful churches is different than the way our Heavenly Father test its for fruit of the spirit not fruit of the flesh..

But Jesus Christ looks at the hearts of men not at the building or the music, or its membership. And the problem with the church of Sardis was a failure to measure up to Christ's desires for the body, for they were not the light in a dark land but were infact themselves walking in darkness. He told them, "I know your works, that you have a name that you are alive, but you are dead. Be watchful, and strengthen the things which remain, that are ready to die, for I have not found your works perfect before God" (Revelation 3:1–2).
Another translation of the word "perfect" would be "fulfilled." Jesus was telling them, "You have not fulfilled your purpose." Are we fulfilling our purpose? What is Jesus calling you to do for His name sake? Perhaps He is calling you to pray for your neighbor, your boss, your spouse, your children, the body etc... Perhaps he is  calling you to volunteer to help out in childcare at the church or Sunday School department, or help clean the church or host a weekly bible study at your home, not to lead but just host it.  Why are we not seeking to know the will of Christ for our lives, should we not seek that to ensure that whatever we are doing it is God's perfect will and that we bring him glory. What kind of Church are you helping create, what message does your body reflect to those outside? Are you a gateway for people to come to Christ? Or are you road block in the way of those wanting to come to Jesus? I know the Church we need to be is the one that Christ is returning for which is one on fire for the Lord, that is producing good fruit.
