Why are molecules with more resonance forms more stable?

I keep reading this in my book and can't find the reason why...

Because of possible delocalization of electrons, thus stabilizing the compound.
See keto-enol relationship, if ketone treated with strong base (which isn't a good nucleophile) and an alpha-hydrogen is removed you may stabilize it by donation of electrons from oxygen/carbonyl.
