The painting is an oil on canvas, showcasing Redon's signature style of blending realism with dreamlike elements. The brushwork is fluid, contributing to the overall sense of motion in the piece. The angel's expression is both serene and powerful, embodying the duality of divine presence.

Interestingly, Redon often drew inspiration from literature and mythology, which is evident in this work's title referencing a biblical passage.

The painting invites viewers to contemplate the nature of divine intervention and the mysteries of existence.
