Why is Christ described as the righteous King in Psalm 45?

Psalm 45 portrays Christ as the righteous King, a reflection of His divine nature and moral perfection. The psalm highlights His love for righteousness and hatred for wickedness, underscoring the holiness that characterizes His reign (Psalm 45:7). This righteousness is not only an attribute of His character but also is imputed to believers, as seen in 2 Corinthians 5:21 where Christ, who knew no sin, became sin for us that we might become the righteousness of God in Him. Hence, His kingship is marked by justice and truth, which are fundamentals of His governance.
