Why is Jesus referred to as having eyes of fire?

In Revelation 1:14, the description of Jesus' eyes as a flame of fire serves to illustrate His omniscience and holiness. The fire signifies purity and the ability to discern truth from falsehood and righteousness from sin. This imagery indicates that nothing is hidden from Christ; He sees into the depths of our hearts, exposing our true nature. For believers, this should bring both comfort and accountability, knowing that He inspects our inward motivations and offers grace to those who seek Him with a sincere heart.
