No net force. If there is a a net force, then there will be acceleration proportional to the force and inversely proportional to the mass of the object.
So, as long as we are not talking about a zero time span, i.e., at rest means resting over a period of time, then the sum of the forces acting upon an object remaining at rest must be zero.

If there is a net force the object is moving. The velocity at which it is moving would be proportional to its mass. (F=ma) An object at rest has a net force of zero. Think tug of war with no winner.....there is a lot of force pulling on the rope but the net force (i.e. someone in the mud pit) is zero.
