How do I label a point on my 3D parametric equation plot?

GROUPS:
Hi all,

I am having a hard time figuring this out. I have a parametric curve (3D) f[t_] = {4 - 2 t, 2 + t, 8 - t} and I need to label a specific point in the 3D plot at (2,1,3). How do I do this?

Show[{
  Graphics3D[{PointSize[.02], Point[{2,1,3}]}],
  Graphics3D[Text[{2,1,3}, {2,1,3}, {-2,0}]],
  ParametricPlot3D[{4-2t, 2+t, 8-t}, {t,0,4}]
  }]
