Angels are not tied to our three dimensional reality. They have no concept of time and space, moving freely between our world and theirs. An angel’s movement is as quick as a thought. The great archangels can be in several places at one given time. Don’t be afraid that your personal dilemma is too significant to lay before an Archangel, or that you will not be heard.
There are major catastrophes in the world and these need great shifts of understanding and human intervention. These are overseen by archangels at every given moment, but so are you. The archangels do both. The energetic loving energy they emit is beyond our human understanding.
A true request, for the right reasons, is never too simple nor too small to be heard by the angels. You are loved and important. Never forget that.
