Here is a great quote that is full of life, truth and wisdom by Dr. Steve McVey: 

Grace is irrational to the thinker. It is unfair to the judge. Grace is foolishness to the achiever. It is a waste to the selfish. Grace is a mistake to the disciplinarian. It is shame to the religionist. But it is a stream of water to the thirsty. It's freedom to the imprisoned. It is life to the dead. Grace is rest to the tired. It is another chance to the failed. It is hope to the despondent. It is a way out for the last and a way in for those who can see the door.
