In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. All things were created through Him, and apart from Him not one thing was created that has been created. Life was in Him, and that life was the light of men. That light shines in the darkness, yet the darkness did not overcome it.
John 1:1-5 HCSB
Jesus is the Light of the world, and He alone defeated the darkness of the devil. With Jesus at our side, evil cannot overcome us.
When troubled, call on the Lord.
When challenged, call on the Lord.
When victorious, call on the Lord.
Rejoice in all things before the Lord!
