Psalm 57:7-11 (NRSV)
7 My heart is steadfast, O God, my heart is steadfast. I will sing and make melody. 8 Awake, my soul! Awake, O harp and lyre! I will awake the dawn. 9 I will give thanks to you, O Lord, among the peoples; I will sing praises to you among the nations. 10 For your steadfast love is as high as the heavens; your faithfulness extends to the clouds. 11 Be exalted, O God, above the heavens. Let your glory be over all the earth.
Romans 13:11-14 (NRSV)
11 Besides this, you know what time it is, how it is now the moment for you to wake from sleep. For salvation is nearer to us now than when we became believers; 12 the night is far gone, the day is near. Let us then lay aside the works of darkness and put on the armor of light; 13 let us live honorably as in the day, not in reveling and drunkenness, not in debauchery and licentiousness, not in quarreling and jealousy. 14 Instead, put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.
Ephesians 5:14 (NRSV)
14for everything that becomes visible is light. Therefore it says, “Sleeper, awake! Rise from the dead, and Christ will shine on you.”
