1. Johannes 1:5

First division of the body of the Epistle (compare Introduction). declare--Greek, "announce"; report in turn; a different Greek word from Jo1 1:3. As the Son announced the message heard from the Father as His apostle, so the Son's apostles announce what they have heard from the Son. John nowhere uses the term "Gospel"; but the witness or testimony, the word, the truth, and here the message. God is light--What light is in the natural world, that God, the source of even material light, is in the spiritual, the fountain of wisdom, purity, beauty, joy, and glory. As all material life and growth depends on light, so all spiritual life and growth depends on GOD. As God here, so Christ, in Jo1 2:8, is called "the true light." no darkness at all--strong negation; Greek, "No, not even one speck of darkness"; no ignorance, error, untruthfulness, sin, or death. John heard this from Christ, not only in express words, but in His acted words, namely, His is whole manifestation in the flesh as "the brightness of the Father's glory." Christ Himself was the embodiment of "the message," representing fully in all His sayings, doings, and sufferings, Him who is LIGHT.

The apostle, having declared the truth and dignity of the author of the gospel, brings a message or report from him, from which a just conclusion is to be drawn for the consideration and conviction of the professors of religion, or professed entertainers of this glorious gospel. I. Here is the message or report that the apostle avers to come from the Lord Jesus: This then is the message which we have heard of him (Jo1 1:5), of his Son Jesus Christ. As he was the immediate sender of the apostles, so he is the principal person spoken of in the preceding context, and the next antecedent also to whom the pronoun him can relate. The apostles and apostolical ministers are the messengers of the Lord Jesus; it is their honour, the chief they pretend to, to bring his mind and messages to the world and to the churches. This is the wisdom and present dispensation of the Lord Jesus, to send his messages to us by persons like ourselves. He that put on human nature will honour earthen vessels. It was the ambition of the apostles to be found faithful, and faithfully to deliver the errands and messages they had received. What was communicated to them they were solicitous to impart: This then is the message which we have heard of him, and declare unto you. A message from the Word of life, from the eternal Word, we should gladly receive: and the present one is this (relating to the nature of God whom we are to serve, and with whom we should covet all indulged communion) - That God is light, and in him is no darkness at all, Jo1 1:5. This report asserts the excellency of the divine nature. He is all that beauty and perfection that can be represented to us by light. He is a self-active uncompounded spirituality, purity, wisdom, holiness, and glory. And then the absoluteness and fulness of…

1:5–2:6 Here John focuses on the first aspect of living in fellowship with God. Living in the light means that the believers will see that they are sinners, but they will also realize that Jesus is their Advocate to make them right with God (see Eph 5:6-13). 1:5 God is light: This light shone through Jesus Christ to all he came in contact with, to expose their sin and to illumine the moral nature and character of God (see John 1:4-5, 9; 3:19-21; 8:12; 9:5; 12:35-36, 46). In the writings of John, “light” represents God’s holiness and revelation. It is the opposite of false teaching and undisciplined living, which is “darkness” (1 Jn 1:6).
