Are you trying to refer to angels here? Or somehow law of attraction?
Sometimes you may not know what you need help with; you just have a general feeling of struggling in life and needing help. That's fine, the Universe knows you and your life, and knows exactly what you need help with. If you are general with your affirmation and your belief, you will start to attract the help you need ANYWAY, with the things that you need help with. As with anything and everything in your life, the Universe is just waiting for you to invite it in (by giving it your permission to enter your life) and get to work on helping you and resolving things.
Thank you Sir Neil :)
The divine created you and everything else, why could it not help you with a problem?
