What does looks can be deceiving?

Answer 1

Someone may be putting on a show for you but they may have other intentions than what they are leading you onto. Jesus said beware of the wolf in sheep's clothing. He/She might look nice and proper on the outside but may be very different on the inside and may be trying to fool you to fall into their trap. Things are not always as they appear.

Answer 2

This is a cliche or saying that warns people to be careful about relying on first impressions or the way something looks, as these superficial features can hide a very different underlying reality. An example of this is the classic warning about buying a used car - the car may have a really good paint job and have clean, good quality carpeting inside, but the engine (which you can't really see unless you take it apart and examine the individual pieces) may be corroded, not working or about to shatter. In this example, the appearance (good paint, good interior carpeting) deceived (lied, hid, presented false information) about the actual condition of the vehicle (engine is about to fall apart).

Answer 3

There is 99% more to what you see with your human eyes (and the rest of your 4 senses). Therefore, take heed and don't rely on your senses alone to make decisions and place judgement.
