The Light of Joy Replaces the Dark of Sin & Judgement

700 years before the birth of His Son Jesus, God spoke of a people living in the darkness of their sin and the darkness of the judgement and results of sin. Jesus is the Light of the World, and He will, one day, bring for all who trust in Him a full end to all sin and to all the results and judgements of sin. He will replace this darkness with the perfectly satisfying eternal joy of being with God. His second coming He will bring the full realization of it, His death and resurrection accomplished this, faith in Him takes hold of this and gives us a taste of it... but His BIRTH secured this.
