Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
What does that mean to you?
Many people automatically think of the physical. And while physical intimacy is very important in a marriage, it isn't the entirety of one flesh.
One flesh means that you think of your spouse as much as you think of yourself. You want the best for your husband. You want to treat your husband as you would want to be treated. You feel his hurts as if they were your own (even if you don't understand why it hurts). You share things with him that you don't share with anyone else. You support him in his endeavors which means that you don't belittle him or put him down. Stand by his side and encourage him. His success is your success. You are not less of a person because you are a help meet; you are one!
