1 Corinthians 7:2
2 Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.
Do you know how you keep a marriage together? Do you know how you keep temptation out of your marriage? It is simple, keep your eyes on your spouse. Don’t be out there looking at other people trying to figure out if you could do better. That means men are to be married to one wife. That means even if she gets to weigh four hundred pounds. You married her. Women are to have one husband. It doesn’t matter if he gets a gut and his hair falls out. When you take your vows, it is not only a vow between husband and wife. It is also between the couple and God. So, remember your vows and keep your eyes off of other people.
