1QS 1
Community Rule2 He shall admit into the Covenant of Grace all those who have freely devoted themselves to the observance of God's precepts, that they may be joined to the counsel of God and may live perfectly before Him in accordance with all that has been revealed concerning their appointed times, and that they may love all the sons of light, each according to his lot in God's design, and hate all the sons of darkness, each according to his guilt in God's vengeance.
John 12:36
34 Then the crowd responded, “We have heard from the law that the Christ will remain forever. How can you say, ‘The Son of Man must be lifted up’? Who is this Son of Man?” 35 Jesus replied, “The light is with you for a little while longer. Walk while you have the light, so that the darkness may not overtake you. The one who walks in the darkness does not know where he is going. 36 While you have the light, believe in the light, so that you may become sons of light.” When Jesus had said these things, he went away and hid himself from them.
Notes and References
"... To turn to another field, in The War of the Sons of Light and the Sons of Darkness we find an irreconcilable opposition between the darkness and the light: the sons of men are divided as they belong to either of these two forces. The same antithesis appears in DSD 3:13 through 4:26, a section which gives us in a brief compass the theology of the Sect. A comparison of this with the Fourth Gospel reveals a striking similarity. In John (12:36) Christians also are the sons of light, and the dualism of the Scrolls finds an echo in the Gospel."
