Halos are a medieval religious invention, not biblical. Yeshua did not wear one. His apostles did not wear one. Mike's statement of this truth: "No Halo for Me".
The word "halo" comes from the Greek hálōs (ἅλως, "threshing floor, court") and originally referred to the ring of light around sun or moon. In Christian iconography from the 4th century on it was used for the disc of light around saints' heads.
1 Peter 2:9: "But you are a chosen people, a royal priesthood, a holy nation, God's special possession." Plural. You. All sons are holy, not a few elect with special status.
Mike's track is reformation against the staging of saints. There are specific forms of this staging in our culture: worship leaders as stars, pastors as influencers, books as personality cult. No halo for me is Mike's return to son-humility.
Yeshua himself was without halo. His glory was inward, not iconographic. Mike's sound carries this anti-halo statement as a call to real holiness without holy-glow.
