Marriage is an important issue in the Christian life.I give some verses, so I'll just look at a few key passages. I hope you will read the selected verses with an open mind, consider the analysis.
Gen. 2:18, 21-24
The Lord God said, 'It is not good for the man to be alone. I will make a helper suitable for him'...and while he was sleeping, he took one of the man's ribs and closed up the place with flesh. Then the Lord God made a woman from the rib he had taken out of the man, and he brought her to the man. The man said, 'This is now bone of my bones and flesh of my flesh; she shall be called 'woman,' for she was taken out of man.' For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.
Here we see the first wedding. We can conclude from this account in Genesis that marriage is God's idea, designed and instituted by the Creator. In these verses we also discover that at the heart of God's design for marriage is companionship and intimacy.
