Hello Paul
Not only do we have guardian angels, but we have all the host of heavenly angels at our call.
In Hebrews 1:14 Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation ?
Matt 18:18 Verily I say unto you, Whatsoever ye shall bind on earthshall be bound in heaven: and whatsoever ye shall loose on earth is loosed in heaven.
I John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
Isaiah 11:2 And the spirit of the Lord shall rest upon Him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the Lord.
Hebrews 1:7 And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire.
Isaiah 1   is a picture of the church today.
