Well, consistency turns out to be one of those things that looks much differently based upon the paradigm one lives from. As a young parent I heard it over and over and over...."Being consistent with your discipline is the most important advice we can give you." This concept spreads out from parenting into all situations where people are attempting to manage other people's behaviors. Today looking back I can see clearly that most people are concerned with conformity and control instead of the other person's freedom.
If Law is the operating paradigm, consistency means applying the rules equally to everyone in every situation (even ourselves). Try as hard as one might try to do this...history and personal experience proves that it is just not going to happen. And even if the desired end product of uniformity was possible to achieve...how boring and unlivable it would be.
If love and grace is the paradigm from which we live, consistency takes on such a different meaning/feeling altogether. All the models are useless. There is no pattern to follow and end product is no longer the focus. Turns out that the process is where life in all it's wonder and messiness and pain happens.
