One of the changes in the new tranlastion of the Missal that caused some upset was the return to translating rogare as "to beg" instead of the 70's version "to ask." Many people could not seem to reconcile the idea of us having to beg a God who is all loving.
The begging makes sense if we remember that we pray to the Father, through the Son, and in the Spirit. It is a familial relationship. Our baptism makes us the adopted sons and daughters of God. Now think back on your childhood. Didn't we all beg our parents at some point. When we really, really, really wanted something, we could beg like crazy. I can certainly remember myself
Please, please, please please,pleeeeeeeeese....
Yes in prayer we are called to be beggars. But we are not the begger on the street with his hand out, calling to strangers. We are the child begging their loving parent. We beg because we want from the bottom of our hearts. And if we don't get what we want, we may get angry and pout, but deep down inside we know that when the answer is not the one we want, it's still what's best for us.
