1 Corinthians 7 Marriage is an agreement entered into before witnesses and usually registered by state officials, whereby one man and one woman agree to live together. This means that everyone knows their intentions and the marriage should form a sound basis for bringing up children who can feel secure as part of a family.
Christian marriage is that and much more.
The promises made before witnesses are also made in the presence of God, and they are lasting promises. The divine ideal is that one husband and wife should live together always. This is the foundation of a happy Christian marriage - husband and wife who live to help, strengthen, and enjoy one another, in the daily awareness of the presence of God. Although God made man and woman to live together, this is not compulsory - some people do not need or want the company and support of a husband or wife. When two children of God are married before God it is for life.
