Ephesians 5:8-16

For once you were darkness, but now you are light in the Lord; walk as children of Light [lead the lives of those native-born to the Light]. For the fruit (the effect, the product) of the Light or the Spirit [consists] in every form of kindly goodness, uprightness of heart, and trueness of life. And try to learn [in your experience] what is pleasing to the Lord [let your lives be constant proofs of what is most acceptable to Him]. Take no part in and have no fellowship with the fruitless deeds and enterprises of darkness, but instead [let your lives be so in contrast as to] expose and reprove and convict them. For it is a shame even to speak of or mention the things that [such people] practice in secret. But when anything is exposed and reproved by the light, it is made visible and clear; and where everything is visible and clear there is light. Therefore He says, Awake, O sleeper, and arise from the dead, and Christ shall shine (make day dawn) upon you and give you light. [Isa. 26:19; 60:1, 2.] Look carefully then how you walk! Live purposefully and worthily and accurately, not as the unwise and witless, but as wise (sensible, intelligent people), Making the very most of the time [buying up each opportunity], because the days are evil.
