If i try to contact my guardian angel, will god be mad or jealous?

As I understand the system you are to make your request known to God and He will assign which ever Angel He feels is best to answer your request/need. We are not to make our request to the angels or to any dead humans for that matter, We are to ask Jesus and He will ask His Father God and God will assign the person who answers our prayer. God will bring it to pass if that's His Holy Will. If He says NO! He will make a way for us to have something better. Fear no only believe.
