Your artwork should be given its proper chance to shine, and this is why artists use varnish. They can protect the painting from unavoidable elements when it is being transported. Most artists would also recommend applying varnish if your painting were displayed outdoors or in a very humid environment. For some mediums like acrylic, using varnish can even add gloss or sheen.
