In this passage, Paul is saying, "Jesus is a good Husband. A husband ought to love his wife as Christ loves the church. He gave himself for her and cleansed her by the washing of water through the Word."
If a man is to wash his wife with the Word, just as Christ washes His bride with the Word, he certainly needs to be filled with the Word, just as Christ is filled with the Word. You can't wash if you don't have any water.
Jesus emphasized the importance of the Word in our lives. A male who wants to be a real man--the man God created him to be--has to be full of the Word of God. There is only one way to get clean water: go to the well. You can't wash with unsanitary water of the world. When you fill your mind and heart only with things such as television and sporting events, that's unsanitary water. Some men are washing their wives and children with it. If you want the water that the Manufacturer intended you to have, you need to stay connected to the well of God, which is filled with the Word. This means consistently reading, studying, meditating on and obeying the Scriptures; which is the constitution of God. It is also maintaining your relationship with Jesus and manifesting His nature and character, because Jesus is the Word.
Constitution: John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
