If the angels are spirits, what is the difference between the angels and the Holy Spirit?
The Holy Spirit is God – eternal without origin…the angles are ministering spirits…they are created, they are not deity. God is also a Spirit (John 4:24) and this is the natural form for those living in the Spiritual Realm…a Realm that surrounds us, a Realm far superior to our temporary Realm of Time. God is Spirit and God created the Angels as spirits to interact within the Spiritual Realm like we humans are created with a body of flesh to interact within the physical World…we are also “spirits” encapsulated within a body of decaying flesh that will die away and we will then enter the Spiritual Realm in our disembodied spiritual form, a “few” to glory – “many” to Hades awaiting Judgment (Matthew 7:13-14; Luke 16; Rev 20:11-15) and we will see God as He is (2 Corinthians 5:8; 1 John 3:2)…first in spirit then in the resurrection and the faithful in Jesus will receive a resurrected body like that of Jesus Christ (Philippians 3:21) and we will serve Jesus in our resurrected bodies in the New Jerusalem, forever.
Jesus plainly tells us that He is NOT of this Realm of Time…but Jesus’ Kingdom is in the Spiritual Realm…
