Three things to draw from Genesis about marriage:
1. To have a happy home, you must be ready to die to self. A good home must be borne out of a dead man. Genesis 2:21. You cannot truly love another selflessly and rightly according to God's standards until you die to self. You must practice forgiveness and forgive even those who do not deserve forgiveness. Ephesians 4:32. You must learn to lose a battle to win a war: pick your battles. It is part of oneness that you let go of your privileges.
2. Purpose: God gave Adam a job before he gave him a spouse which points to the fact that one of the ways to have a happy home is to get an office. Genesis 2:15. God did not design us to be idle, if you are, you are straining from God's natural order because Idleness is dangerous. Build support systems for each other apart from each other. Find wise older women to befriend and find wise older men for your husband to befriend.
3. Man is the head of the home: psychologically, when a woman is with the right man, she’ll let him lead. Ephesians 5:22, Colossians 3:18-22. Don’t marry a man whose leadership you do not trust.
4. There is a level of sacrifice and empathy required to make marriage work.
When you notice that you’re falling out of love, you need to learn that love is a command. Acting like a man “in love” he became in love. Look at your woman and “call her” what you want her to be. Call your partner what God has called them. Change your perspective. Be a doer and not just a hearer.
