Intimacy: Marriage Superglue

Intimacy is the glue that bonds a marriage together.  Before applying the glue a couple must make sure they are compatible and fit together spiritually, socially, and temporally before applying the glue. Intimacy before marriage can hinder instead of help our ability to determine compatibility with our partner. Intimacy before marriage can conceal rather than reveal that there is something missing in our respect, love, or spiritual connection.
