In the beginning God created marriage betwen one man and one woman.
In the second chapter of Genesis God saw that Adam was alone and needed a help meet. So he took a rib from Adam's side and made Eve. Therefore this says that the male and female are the complete likeness of what God intended.
The first marriage was performed by God. It was good. It was perfect. But then sin entered the picture.
Man started to think himself as superior to his wife. Commuication broke down. Divorce was allowed, but we must understand, God hates divorce. It was not an option that God put on the table.
When sin and self reign supreme, marriages are heading for failure. If so we need to confess to God (1 John 1:9 "If we confess our sins He is faithful and just to forgive us our sins...) and to our mate.
Planning, practice and prayer are needed., At the altar we said something like "Till death do us part."
Step back and communicate. Learn the love language of the other. Discover the temperament and interests of your mate. You are not the mind reader nor is she. Don't look for solutions outside the marriage. Get into the scriptures. Pray. Build hedges of protection around the marriage and your house. Don't let the world mold you. Be molded by God and the Bible.
It is work, yes, but enjoyable when the two of you are heading in the same direction.
More is to come. Doctrine covers a vast field. This is one of the practical aspects of the field. Feel free to comment and use my knowledge. I want to help you.
Got you with that title, didn't I? The Bible has a lot to say about the subject of sex. In fact, a whole book is in the Bible about sex. For those in the know they will flash to the Song of Songs or the Song of Solomon. It is known both ways. It is about love between Solomon and one of his wives. It details courtship,the wedding and after.
