Ephesians 5:26-27

Ephesians 5:26 That He might sanctify her, cleansing her by the washing of the water in the word,

Ephesians 5:27 That He might present the church to Himself glorious, not having spot or wrinkle or any such things, but that she would be holy and without blemish.

Through the sanctifying, cleansing, nourishing, and cherishing Christ will gain a glorious church as His Bride. Just as Eve came out of Adam and went back to Adam to be one flesh with him, so the church comes out of Christ and will go back to Christ to be one spirit with Him. God's desire is that the church which comes out of Christ and returns to Christ will be glorious church, a church that expresses God and manifests Him. By the sanctifying, cleansing, nourishing, and cherishing the church is being saturated with the essence of God. In this way the church is becoming the Bride to express Christ. Every local church must be such an expressing of God. 

The glorious church, the church that expresses God, must also be holy and without blemish. As such a holy church, she must be first separated from everything common and then permeated and saturated with the element of God.
