Why are positive G values representative of instability for the given molecule?

Molecules in nature tend to proceed toward their most stable state. A chemical reaction with a positive Gibbs free energy is nonspontaneous, which means energy is required to move the molecule from its current state to a less stable state (for were the reaction spontaneous, no energy input would be needed, as molecules already by nature tend to proceed toward stability).
