The Angels are constantly looking out for you and what is in your best interest. As such, they will not pass on messages without your consent. And, as we all have free will, the big Guy, the big Gal, Universe, Spirit, the Angels, they all cannot ignore our right to make our own choices.
In fact, the only way anyone can bring in messages from your Angels to you is with your permission. But once you grant this, your Angelic team will step in to offer their beautiful messages of love, warmth, and sometimes necessary words of a caution that are meant for you, and you alone.
