<p>5:5 <i>For you are all sons of light and sons of the day. We are not of the night, nor of darkness</i>- &quot;Sons of light&quot; was the language of Judaism for the hyper righteous within Israel. Remember that the Gentile Thessalonians had been synagogue attendees whom Paul had persuaded. He was saying that they, in Christ, were the true &quot;sons of light&quot;. &quot;The day&quot; surely refers to the Kingdom; we recall Rom. 13:12,13 (see note there): &quot;The night is far spent, and the day is at hand. Let us therefore cast off the works of darkness and let us put on the armour of light. Let us behave decently, as in the day&quot;. We are to live the Kingdom life now; in this sense, we &quot;have eternal life&quot;, and that we are to live now as we shall eternally live. We are &quot;the sons of the day&quot; in that we are &quot;the children of the Kingdom&quot;, another phrase understood by Judaism to refer to the righteous Jews- whom the Lord said would be cast out into the darkness of condemnation (Mt. 8:12). &quot;Darkness&quot; is so often associated with the condemnation of the last day; we are not to live the life of the condemned, but of those who shall eternally live the Kingdom life.</p>
