"Take no part in the unfruitful works of darkness, but instead expose them. For it is a sham even to speak of the things that they do in secret; but when anything is exposed by the light it becomes visible, for anything that becomes visible is light. Therefore it is said, 'Awake, O sleeper, and arise from the dead, and Christ shall give you light.'" Ephesians 5: 11-14
Notes from my Bible:
5: 14 - awake O sleeper: Possibly an excerpt from an ancient baptismal hymn. it resonates with the surrounding themes of light, symbolic of purity and truth, and darkness, symbolic f sin and ignorance (5: 7-13). The summons to 'arise from the dead' is a call to break away from the sinful world and live as children of light (5: 7-8; 2 Cor 6: 14).
