Angels are everywhere. They are in heaven and they are in the earth and they are with you right now. They could be sitting next to you on a bus, train, be next to you in an elevator, at the grocery store, or just anywhere.
Angels have access to earth through an open heaven by means of obedience to God, our worship and the Word of God.
Gen 28:12 And he dreamed, and behold a ladder set up on the earth, and the top of it reached to heaven: and behold the angels of God ascending and descending on it. KJV
This spiritual ladder Jacob saw revealed angels having access to earth and coming and going back to heaven to help aid and serve the children of God.
Angels live in the realm that is invisible to the natural eye but does exist. This invisible realm is more real than the natural realm where we perceive things by the five natural senses. But through our spiritual senses we are able to perceive things in this invisible realm.

You wouldn’t want to be on this earth without your angel and other angels looking after you or assisting you. The recordings in the bible of God’s people interacting with angels and receiving their assistance prove we need the assistance of angels and I hope you are realizing that more than you ever have before.
Ps 24:1 The earth is the LORD's, and the fulness thereof; the world, and they that dwell therein. KJV
Since the earth’s fullness and the whole world belong to God, God’s angels doing God’s bidding are dispatched to every parcel of land, every piece of dirt, every drop of dew, every piece of matter and to us. Angelic hosts fill the heavens and live in God’s Presence 24/7.
Angels love us as does our dear heavenly Father and so we must be assured we are surrounded by innumerable angels sent by our Father to minister to us on this spiritual journey through life on planet earth.
Heb 1:14 Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation? KJV
There are angels on planet earth because there are also demons on planet earth who come to kill, steal and destroy the people of God. We must become more and more aware of their presence to help us so that we are not destroyed for a lack of knowledge.
Hos 4:6 My people are destroyed for lack of knowledge: KJV
Our warfare is not with flesh and blood and so angels are here to war against the demonic that opposes us on every single day, every single hour of the day.
