Couples deceive each other in many ways. Sometimes spouses lie over small things, such as spending too much. At other times, they lie about serious things, such as affairs. In our way of thinking, anything, large or small, is forgivable and able to be worked through in a relationship—except deception. Deception is the one thing that cannot be worked through because it denies the problem. It is the one unforgivable sin of a relationship because it makes forgiveness unattainable.
