The Messages of Truth by Deborah Waldron Fry

I am sending My Messengers to you, Beloved. You will entertain angels unaware. They may not appear to you in a way that you would think or imagine. They are bringing messages of Truth. Test the spirits, My Child. They always point you to My Word and My Son. You will know them by the JOY you feel. JOY and NOT fear, Dear One. In My Presence is FULLNESS of Joy. Your angels are forever before My Face. You will receive instructions in the night by My Spirit. I am sending you dreams and visions.

You are in this world, but not of it. Do not be surprised by the marvelous things I will do for you, the things I will show you, and the words I will speak to you. This is normal in My Kingdom. You are a citizen of heaven, the supernatural realm, Dear One. Be expectant.

"You are My witnesses," declares the LORD, "And My servant whom I have chosen, so that you may know and believe Me and understand that I am He and there is no Savior besides Me." What you hear whispered in your ears, Beloved, shout from the rooftops. For surely the Lord GOD does nothing unless He reveals His secret counsel to His servants the prophets. A lion has roared! Who will not fear? The Lord GOD has spoken! Who can but prophesy?…

Smith's Bible Dictionary - Angels
By the word "angels" (i.e. "messengers" of God) we ordinarily understand a race of spiritual beings of a nature exalted far above that of man, although infinitely removed from that of God--whose office is "to do Him service in heaven, and by His appointment to succor and defend men on earth."
