Spontaneous Reactions and Relation to Delta G°

If a reaction is spontaneous, why does that imply that Delta G°of the reaction is positive?

Delta G is negative for spontaneous reactions.
If you see the equation for delta G: delta G(system)=delta H(system)-T*delta S
The sign for delta G is the opposite for delta S of the system
And since delta S has to be positive for spontaneous, delta G is negative.
