That Christ is the Head of the church, What does the Bible mean exactly when it says, a man is the head of his wife, it which sense?

He is the protector and teacher of his wife in other words.

To Understand The husband & wife roles better I found understanding Jesus' Role as Bridegroom to the Bride, Reveals more of the Mystery of Marriage. God created this Big thing called Marriage. He has the Manual for it. Mankind has taken God Instituted things, and moved God out of the equation hence our devastatedly fallen state. The Amount of Divorces, missing fathers and broken families thus broken individuals in our world is Astounding. Yet sadly the Vast Majority Stubbornly Insist on trying to do mariage without its Very Manufacturer.
Even Christian husbands Miss it. I believe a Wave of Revelation is about to hit this earth About Marriage & God will be Healing MANY marriages! Marriage is Supposed to be a Powerful Wordless Witness to the Unsaved. They are Supposed to be Drawn to Gods Love for them by Merely Witnessing the Level Of Love Interaction between the Bridegroom and the Bride. The same goes for our Personal Relationship With God though Jesus. The Husband therefore can only ever be a True head of the Wife IF Jesus is truly his Head. Is his Heart surrendered and in Submission to His Head? No he doesn't have to be perfect or perfectly relgious. (A woman will Know Honesty and Sincerity when she sees it, God WIRED us this way). Then the husband will be a 'True' head of the home that a "wife CAN submit to JUST AS SHE WOULD SUBMIT TO THE LORD. any other " head" is false and a wife not is asked to submit to that.

Ephesians 5:25 The Husband is to Love the Wife Just As Christ Loved the Church. Christ is Head of the church. What did he Do for her? For His Bride? He Loved Unconditionally. He Willingly Laid HIS Life down. He MADE the FIRST MOVE. and Then She RESPONDED. The Head of the wife then should Do Likewise. A man was created to INITIATE hence him being the Hunter. The Church/Bride only then Responded. Woman are designed with REPRODUCtive organs & hormones. Therefore the Wife is a RESPONDER to the INITIATOR (The Head) Only the Man has the seed of life. It is impossible to give the man LIFE, Unless he gives it FIRST. then we give back. This system Father created Works in All its PRINCIPLES of SOWING & REAPING which He said in Genesis must Bear After its own Kind. So if the Head is Not sowing Life then he is by default Sowing Death into the marriage. and one way or another it will Show.
