Armand Nigro, SJ, urges us to pray for what we want:
When we beg God for sunny weather, or pray that our bursitis will go away, or pray for something more holy or important such as international peace and justice we pay a great compliment to God. This is an expression of “becoming as little children” which Jesus recommended, and honored. A child who comes to his parents and asks for things is paying them a big compliment. What is the child saying but, “You are good and can fill my needs. Please, may I have a candy bar?”
When we approach God with this sense of our absolute dependence, and need, we are conscious of being precious and important, but without Him of being nothing, because all that we have is loved into us by God. In this consciousness, we are profoundly acknowledging what He is and what we are.
