Humans are God's pure beings his perfect creations not the Angel's hence the great rebellion when the Angel's were told to bow to his creation.

Your Angel's your personal Angel's and others are here at your command to help you .
Your Angels take directions from you and, are here to help you you can even send your angel's to protect others.

Angels can't intervein as example, you have a job interview ask the Angels nothing whole interview sucks you walk out the door and miss a step and bam broke ankle .
Or You can direct your Angel to pave the way of all obstacles , interview goes great job is yours with extra money for expenses and some old lady missed the step and you caught her preventing her fall.

I direct my Angel's and Ancestors in my life with great success so either it works or I have the greatest luck in the world.
