...Where, then, is God�s justice, for whilst we were sinners, Christ died for us!"
So we see that God is not just, with the human meaning of this word, but we see that His justice means His goodness and love, which are given in an unjust manner, that is, God always gives without taking anything in return, and He gives to persons like us who are not worthy of receiving.
James Ferrenberg sent me this (long) article. Lots to think about.
