It should be pretty obvious that happy wife, happy life is wrong. I’ve been trying to think up a better maxim which is theologically sound.
Ephesians 5:25 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.
“Sanctified wife” is obviously what all husband should aim for as to emulate Christ’s love.
As one is sanctified and filled with the Spirit, the fruit of the Spirit become manifest.
Galatians 5:22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law.
1 Thessalonians 5:16 Rejoice always; 17 pray without ceasing; 18 in everything give thanks; for this is God’s will for you in Christ Jesus.
Sanctification of both the husband and the wife should result in the peace and joy of the Spirit becoming manifest throughout the marriage, which is a witness to both non-Christians and Christian marriages that are not.
