According to Newton's first - law, an object at rest stays at rest unless acted upon by an unbalanced force. When two equal forces act on an object in opposite directions, the net force is zero, so the object remains stationary. Gravity pulls downwards and a normal force (from the surface it's on) pushes upwards with equal magnitude, creating a balanced - force situation. Forces in the same direction would cause acceleration, and gravity doesn't "hold up" an object but rather pulls it down.
