The grace of God means something like: Here is your life. You might never have been, but you are because the party wouldn't have been complete without you. Here is the world. Beautiful and terrible things will happen. Don't be afraid. I am with you. Nothing can ever separate us. It's for you I created the universe. I love you. There's only one catch. Like any other gift, the gift of grace can be yours only if you'll reach out and take it. Maybe being able to reach out and take it is a gift too.
Of the Seven Deadly Sins, anger is possibly the most fun. To lick your wounds, to smack your lips over grievances long past, to roll over your tongue the prospect of bitter confrontations still to come, to savor to the last toothsome morsel both the pain you are given and the pain you are giving back--in many ways it is a feast fit for a king. The chief drawback is that what you are wolfing down is yourself. The skeleton at the feast is you.
Lust is the craving for salt of a person who is dying of thirst.
Envy is the consuming desire to have everybody else as unsuccessful as you are.
Despair has been called the unforgivable sin--not presumably because God refuses to forgive it but because it despairs of the possibility of being forgiven.
