Memo to God: I've been demanding and demanding things from You, often quite rudely, in fact often very rudely, like an ill-bred spoilt child, but I think prayer must have made me better mannered or perhaps it's helped me grow up a little and now I should like to say politely: "thank you very much" -- not just for staying with me no matter how unpleasant I was, but for actually moving closer and surrounding me with people who care.
For the blessed souls who have entered the profound union of divine life: rest and activity, contemplation and action, silence and speaking, receiving the gift of God in love and returning love by waves of thanksgiving and praise, are the same thing.
