In 2008, a book was published called When Good People Have Affairs, giving seventeen motives for people committing adultery.
One motive is the “accidental affair.” This is when a woman has an innocent drink with her boss, and then goes back to his apartment to discuss business and ends up in bed with him. I am sure her husband will completely understand the next day when she tells him that she accidentally committed adultery.
The dilemma regarding how to define “good” is resolved by looking at how God defines it. In His Book, “good” means moral perfection, in thought, word, and deed. In that case, none of us is good. Therefore, the book’s title is an oxymoron, because good people don’t commit adultery. Sinners do, and sinners who commit adultery will receive terrible justice from a holy God for transgression of His Law.
Jeremiah 29:23 because they have done disgraceful things in Israel, have committed adultery with their neighbors’ wives, and have spoken lying words in My name, which I have not commanded them. Indeed I know, and am a witness, says the Lord.
