Temperature is a property of matter, and space is not matter. So, space itself isn't cold, things in space are cold. Or warm, as the case may be. How the radiation from the sun affects you depends on how far away from it you are. If you orbit the sun in the same orbit as Mercury, you'll be crisp in no time.

Is that because space itself is a void? Then why does something in space, say liquid water, freeze once exposed to space? What is conducting the heat out of the water? Where does the heat go?
JonF answered this much better than I could have. Thanks, JonF.
