Men who are married should be fulfilling the following Scriptures in their marriage or have a plan to do so. The practical application is that men must be leading their home spiritually and their wife must confirm this.
The reference letter/email from their wife must confirm or deny that the husband is applying each of the three following Scriptures.
1 Peter 3:7, Colossians 3:19, Ephesians 5:25-33a
You husbands in the same way, live with your wives in an understanding way, as with someone weaker, since she is a woman; and show her honor as a fellow heir of the grace of life, so that your prayers will not be hindered. 1 Peter 3:7
Husbands, love your wives and do not be embittered against them. Colossians 3:19
25 Husbands, love your wives, just as Christ also loved the church and gave Himself up for her, 26 so that He might sanctify her, having cleansed her by the washing of water with the word, 27 that He might present to Himself the church in all her glory, having no spot or wrinkle or any such thing; but that she would be holy and blameless. 28 So husbands ought also to love their own wives as their own bodies. He who loves his own wife loves himself; 29 for no one ever hated his own flesh, but nourishes and cherishes it, just as Christ also does the church, 30 because we are members of His body. 31 For this reason a man shall leave his father and mother and shall be joined to his wife, and the two shall become one flesh.32 This mystery is great; but I am speaking with reference to Christ and the church.33 Nevertheless, each individual among you also is to love his own wife even as himself….. Ephesians 5:25-33a
