The result of this will be split on words.  That is not what you want.

Yes.  Read would be quite a better way to do it.

That above makes no sense to me.

Try something more like this:

  while read line ; do
    echo "$line"
  done < config.txt

Can you simply keep track of the line numbers yourself as you go along?

  lineno=0
  while read line ; do
    lineno=$(($lineno + 1))
    echo "$lineno: $line"
  done < config.txt
