Electric field inside a sphere of charge

So I understand that to find the electric field inside a sphere of charge you can use Gauss's Law by drawing a sphere inside, enclosing the charge. But, intuitively, I don't understand it.. why don't the charges outside this sphere contribute to the electric field? I know the total flux through the sphere you've drawn will be zero, but I don't know, it just doesn't make sense visually to me.

The fields due to the charges outside the sphere all point in different directions. The vector sum of these fields, as it turns out, adds up to zero.
