@Beetow -- part of marriage are the adjustments that the man and woman make as a married couple -- marriage should be the most important decision in a person's life -- salvation being the Most important decision.
Communication is probably the most important aspect of Any relationship. Being able to talk / share with the other person as well as listening to them.
Biblically -- transgenders don't really exist -- gays and lesbians are not living in a Biblical life-style. Thereby, creating their own set of problems. Marriage is meant to be between one man and one woman. When people Choose to stray away From that, there will be problems. God has the answers To those situations. However, people would rather do their 'own' thing than follow God's guidelines.
Married love can be shown through sex. Sex is not 'making' love , it's 'Showing' their love to each other.
Husbands and wives 'complete' each other. Joined together they form 'oneness'. The one-flesh union. The marriage ceremony joins the man and woman legally -- they promise -- vow to each other -- that until death separates them -- they Will be there for each other in times of sickness / health -- in times of being poor or experiencing wealth -- whatever happens -- they will Always be there for each other. They give each other rings to show others that they are married. They won't be flirting with anyone other than their mate. They share everything with God and then their husband/ wife.
There's a book "The Five Love Languages' -- very good.
Was just looking those three up -- Philos - love is that of being a friend or a brother. Agape = God's love for us -- a self-sacrificial kind of love.
So -- shouldn't a husband and wife be friends 1st -- being able to talk about pretty much everything // enjoying each other's company. Wanting to do 'life' together. Day-by-day living. And That would lead To being engaged and then married. And the 'chemistry' experienced When being together. People can be great friends, but experience no 'chemistry' -- And there can be real 'chemistry' between two people and then deciding what to do With that chemistry. The 'chemistry' is what makes the world go around. The 'chemistry' is what causes ya to want to have all that neat physicalness. Which needs to be with the opposite sex and with marriage.
Actually -- you've left out 'eros' love -- sexual / romantic love. THAT is husband / wife love. THAT is the husband / wife love.
A husband has that inner drive to provide for his wife / family. And the wife to be a home-maker, taking care of her husband and children. It's team-work. A Godly home.
When either a guy or a gal are anticipating marriage -- or even dating. They Should be learning about various aspects Of 'life' as part Of growing up ;How to clean a house / to cook. Taking out the garbage --mowing the lawn. Paying the bills on time. Being faithful to your spouse / friends.
Being committed to that one man and having children by that one man -- emotional security for all. Commitment to That relationship and Those children. Emotional security and learning that conflict Can be worked through. It give the children emotional security.
There was a woman from some years ago in our small town -- she'd been married for many years -- she divorced her husband because she was no longer satisfied with Loving -- she wanted to be 'in love' with him. She finally Did get with a man who she was in-love with and they did get married. About 6 months after she divorced her husband, he was found dead. Everything in the house was exactly as when she'd been living there. But her leaving him had broken his heart -- he'd started drinking and drank himself to death. Quite sad.
In a Reader's Digest article from years ago -- a number of couples who'd been together for 30years were asked what kept them together all those years. They all said that they were best friends. they enjoyed spending time together.
Friendship. Godly friends.
