Press 'Tab' during gameplay and you will see a little bracket pop up in the bottom of the screen. Type in 'god' and the screen will say "God Mode On." You still lose health, but when you reach 0 health you still do not die, so it's good to test how enemies will hurt you so you can develop a strategy before playing the game normally.
