Why did Christ give His life for the Church? In order "to make her holy and clean..." Perfection is what Christ is and anyone who is to be related to Him can be nothing less. Perfection is not only true of Christ's character, it is certainly true of the salvation He provided. We had no way to overcome the short-fall of our sinful life. We could never measure up to that which God demanded for entrance into His heaven. Only Christ could give us that perfect standing by saving us with His perfect work at the cross. And once we were clean in His sight we were also seen as "holy", that is, set apart for Him for all eternity. That is what is true of the Church as a whole and what is true of every believer in Christ.
We know we have been cleansed by the blood of Christ, 1 John 1:7,9. But Paul speaks of a cleansing that comes from God's Word. It is through the preaching of the Word that our hearts can be washed clean from doubts and unbelief. As we hear the Word of God He can bring us to be born again. Note 1 Peter 1:23.
Now, how does this relate to a husband's love for his wife. He has the responsibility to help her live a life that is holy and clean before the Lord. No, he cannot save her, but he can minister the Word of God to her, and to himself, to help both himself and her to keep living a cleansed life before the Lord. As a husband ministers the Word to his family he is serving them in one of the most important roles he has in the home. Take time again to read what Moses instructed fathers to do in Deuteronomy 6:1-9. This is a sadly neglected activity in many Christian homes today.
Husbands, do you want to show your wife your love for her? Read and heed God's Word. Read the Word with her and lead her to heed that Word in both her life and yours.
