What role do angels play in God's revelation?

Angels are ministering spirits who observe God’s relationship with humanity, particularly the grace given to sinners through Christ. According to 1 Peter 1:12, angels long to look into the things revealed about our salvation. However, they do not experience grace since they do not require salvation. Their role is to serve God and witness the unfolding of His redemptive plan, which remains a mystery to them, showcasing the unique relationship that believers have with God through Christ. This illustrates the immense privilege of being among those who have been redeemed and understand the depths of God’s grace.
