religious circles, people think that if they are not sleeping with someone other than their spouse, they are being faithful. But faithfulness means to be trusted in all areas, not just the sexual, trusted in matters of the heart as well as those of the body. Being faithful to your spouse means that you can be depended upon to do what you have promised, to follow through on what your spouse has entrusted to you. It means that your spouse can be certain that you will deliver on what you have promised.
