When John turns to see who this is, he sees someone walking in the middle of seven golden candlesticks.  I believe He is inspecting the light of each candle.  Further down in the chapter, we are finding that these are the seven churches spoken of in chapters 2 & 3.  We must remember that this is a vision that John had and Christ will not look like that when we see Him. (There is a lot of symbolism found within these pages that is representative of things yet to come.)  He has this gold like belt at his chest.  Hair white like wool makes Him the Ancient of Days, God Himself.  His eyes are all searching.  His feet are like brass walking in Judgment and who could escape that voice.  The sword of His mouth is that His word is like a sword which pierces deep into our soul and convicts us of sin.  We find this same kind of symbolism in Rev. 19:15.  Other characteristics are written there too.  Each of these are used for the condition that describes each church that we read about in chapters 2 & 3.  I tend to believe they represent not only a specific church but seven time periods of the history of the church.
