“Some people's sins are obvious, preceding them to judgment, but the sins of others surface later” (1 Tim 5:24). Some people are easy to understand; they cannot help but wear themselves on their sleeves, showing their emotions and, sometimes, sins in the open. Others, however, are quite able to keep their sin inside, and take on a form of outward holiness that is at odds with their hearts. God warns us that it is not just what we do, but who we are that matters. Therefore, he commands us “do not covet.”
