Definition: Eros is the physical, sensual love between a husband and wife.
Although this Greek term does not appear in the Bible, eros, or erotic love, is portrayed in the Old Testament book, The Song of Solomon. God is very clear in his Word. Sex outside of marriage is forbidden.
God created humans male and female and instituted marriage in the Garden of Eden. Within marriage, sex is used for emotional and spiritual bonding and for reproduction.
The Apostle Paul noted that it is wise for people to marry to fulfill their godly desire for this type of love:
Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I do. But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion. (1 Corinthians 7:8-9, NIV)
Eros is a necessary part of a healthy marriage.
