The phrase 'sun of righteousness' can only refer to the coming of the Messiah - Jesus Christ. In an age when pagan gods where considered to 'shine' and have 'wings' perhaps Malachi is using these words to reveal the superiority of the coming Messiah. Whatever his motivations, it is a lovely image to think of the 'Son's Rays' reaching out to each one of us.
When we sing the great Christmas Hymn 'Hark the Herald Angels Sing' this year, let us pause at verse 3 and remember that these significant lines point to Jesus:
Hail the heaven-born Prince of Peace!
Hail the Sun of Righteousness!
Light and life to all he brings,
risen with healing in his wings (Charles Wesley)
May we experience the love and healing of Christ this Christmas time. Grace and Peace.
Living in Grace
