Wires are insulated to prevent electrical shock.
Think of electricity in terms of water. Say you hook up a garden hose and turn the handle on the valve. If you instantaneously freeze that picture for a second, there will be high pressure at the beginning of the hose where the water is and no pressure at the end of the hose where the water would come out. Voltage is very similar to that in regards of voltage being a potential difference in electrical pressure.
The insulation on the wire, similar to a garden hose with water, ensures that the electricity follows the intended path.

No wires are insulated to keep you and your home safe and to keep them from grounding out on anything metal and causing fires.
