What does the term 'King of Righteousness' mean in relation to Christ?

The title 'King of Righteousness' ascribed to Melchizedek in Hebrews 7 points directly to the righteousness that belongs to Christ alone. Jesus embodies the essence of righteousness, being fully without sin and the fulfillment of God’s perfect standard. Through His death and resurrection, He establishes righteousness for those who believe, meaning that He not only qualifies as our king but also as the source of our justification before God. This righteousness is not inherent in humanity but is ascribed to us through faith in Christ, emphasizing the doctrine of imputation. Therefore, His title underscores the transforming nature of His work that brings believers into a right standing with God, through which they inherit eternal life.
