Marriage is an amazing picture of what God does for us and in us. Two lives, separate but striving to live together, is a picture that our society does not uphold in the way they should. God reached all the way for us in the person Jesus. We now live linked to Him and attempting to walk in a way that pleases and honors Him. So it is with our lives in marriage. We strive to be one despite all the forces trying to pull us apart.
Some do not get married to accomplish this goal.
Some get married for the wrong reasons and then have to strive to work towards this goal.
Paul spends some time building a great case for marriage and what to do in different circumstances. Remember, this was written to the church that called Corinth home.
Marriage is meant to be a covenantal union of two lives that allows both to honor God instead of dishonoring Him with their choices. If one finds sexual immorality too strong a pull, marriage is the space that proper sexual relationships are formed. In this, neither party are meant to be in this relationship alone. They are to share their lives, bodies, etc.
If you are unmarried, consider staying that way.
If you are a widow, the same is true. Unless you must get married, then do so (see the freedom he explained in chapter 6).
If you are married, share it all.
If you are married to an unbeliever, show them Christ in how you conduct yourself in your marriage. This can be hard, but is crucial!
The rest of the chapter spells this out over and over. It is marvelous. Is your marriage stacking up? Perhaps you two need to talk this chapter out and consider what Paul is saying. If marriage is meant to be a picture of God’s relationship to us, how does your marriage stack up?
