| Geneva Study Bible Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. People's New Testament 5:5 Ye are all the children of light, and the children of the day. They are of the light, of the day, because they have come to Christ for light, and are taught of him. Hence on this subject they are fully informed. We are not of the night, nor of darkness. Those are of the night, who turn away from the light and refuse to accept it. Jamieson-Fausset-Brown Bible Commentary 5. The oldest manuscripts read, "FOR ye are all," &c. Ye have no reason for fear, or for being taken by surprise, by the coming of the day of the Lord: "For ye are all sons (so the Greek) of light and sons of day"; a Hebrew idiom, implying that as sons resemble their fathers, so you are in character light (intellectually and morally illuminated in a spiritual point of view), Lu 16:8; Joh 12:36. are not of-that is, belong not to night nor darkness. The change of person from "ye" to "we" implies this: Ye are sons of light because ye are Christians; and we, Christians, are not of night nor darkness. Matthew Henry's Concise Commentary 5:1-5 It is needless or useless to ask about the particular time of Christ's coming. Christ did not reveal this to the apostles. There are times and seasons for us to work in, and these are our duty and interest to know and observe; but as to the time when we must give up our account, we know it not, nor is it needful that we should. The coming of Christ will be a great surprise to men. Our Lord himself said so. As the hour of death is the same to each person that the judgment will be to mankind in general, so the same remarks answer for both. Christ's coming will be terrible to the ungodly. Their destruction will overtake them while they dream of happiness, and please themselves with vain amusements. There will be no means to escape the terror or the punishment of that day. This day will be a happy day to the righteous. They are not in darkness; they are the children of the light. It is the happy condition of all true Christians. But how many are speaking peace and safety to themselves, over whose heads utter destruction is hovering! Let us endeavour to awaken ourselves and each other, and guard against our spiritual enemies. |
