The best way to answer this question is to draw a diagram like this one

I found that by typing in "rays on a concave mirror" into Google image search.

Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection.

The light rays would be reflected towards the centre of curvature of the mirror. Light that passes throught the focal point pass straight through.
