What does it mean for Christ to be the son of righteousness?

In the context of Malachi 4:2, the term 'son of righteousness' reflects Christ's role in bringing redemption and healing to His people. He is the embodiment of righteousness who dispels darkness and sin with His light. His character and work fulfill the prophetic promise and serve as a comfort to those who acknowledge their need for Him. Just as the sun brings warmth and energy necessary for growth and life, so does Christ bring spiritual vitality and renewal, enabling believers to flourish in their faith and live in accordance with God's will.
