For the life was manifested; and we have seen and do bear witness, and declare unto you the life eternal, which was with the Father, and hath appeared to us:

“"The life was manifested." For in the Gospel he thus speaks: "And what was made, in Him was life, and the life was the light of men." "And we show unto you that eternal life, which was with the Father, and was manifested unto you." He signifies by the appellation of Father, that the Son also existed always, without beginning.”

“"The Life was manifested." Christ therefore is "the word of life." And whereby manifested? For it was "from the beginning," only not manifested to men: but it was manifested to angels, who saw it and fed on it as their bread. But what saith the Scripture? "Man did eat angels' bread." Well then "the Life was manifested" in the flesh; because it exhibited in manifestation, that that which can be seen by the heart only, should be seen by the eyes also, that it might heal the hearts. For only by the heart is the Word seen: but the flesh is seen by the bodily eyes also. We had wherewith to see the flesh, but had not wherewith to see the Word: "the Word was made flesh," which we might see, that so that in us might be healed wherewith we might see the Word. "We have seen and are witnesses." Perhaps some of the brethren who are not acquainted with the Greek do not know what the word "witnesses" is in Greek: and yet it is a term much used by all, and had in religious reverence; for what in our tongue we call "witnesses," in Greek are "martyrs." Now where is the man that has not heard of martyrs, or where the Christian in whose mouth the name of martyrs dwelleth not every day? For it was for bearing witness of that which they had seen, and bearing witness of that which they had heard from them who had seen, that, while their testimony itself displeased the men against whom it was delivered, the martyrs suffered all that they did suffer. The martyrs are God's witnesses.”

“For the life was manifested,.... That is, the Word of life, who is life itself, the fountain of life, having it as God, in and of himself, without derivation from, and independent of another, originally and eternally, and who is the cause, author, and giver of life in every sense to others; this living God, who from all eternity was invisible, was in the fulness of time manifested in human nature; see Joh 1:14. And we have seen it; as before with the eyes of their bodies: and bear witness; for they were both eye and ear witnesses of the Word, and of the truth of his incarnation, and bore a faithful record to his proper deity, and real humanity: and show unto you that eternal life; Jesus Christ, the true God, and eternal life, as in Jo1 5:20; so called, because he has everlasting life in himself; as he is the living God, and because he has eternal life for all his people; not only the purpose and promise of it are in him, but the thing itself; and it is in his power and gift to bestow it on all the Father hath given to him, and to them he does give it. The beginning of it lies in the knowledge of him, and the consummation of it will be in the lasting vision and enjoyment of him: which was with the Father; that is, which life, eternal life, and Word of life, was from the beginning, or from all eternity with God the Father; which phrase is expressive of the eternal existence of Christ, as the Word and Son of God, with his Father, his relation to him, his oneness in nature, and equality with him, and his personal distinction from him; see Joh 1:1; and was manifested unto us; in human nature, as before observed, and that to the apostles, as he was not to the patriarchs and prophets; for though they saw him in promise, in prophecy, in type, and figure, and he sometimes appeared in an human form for a short time to them, yet they did not see him incarnate, in actual union with human nature; nor had they him dwelling among them, and conversing with them, as the apostles had; this was an happiness peculiar to them.”

“For the Life was manifested - The Lord Jesus, who is the creator of all things, and the fountain of life to all sentient and intellectual beings, and from whom eternal life and happiness come, was manifested in the flesh, and we have seen him, and in consequence bear witness to him as the fountain and author of eternal life; for he who was from eternity with the Father was manifested unto us his apostles, and to the whole of the Jewish nation, and preached that doctrine of eternal life which I have before delivered to the world in my gospel, and which I now farther confirm by this epistle.”

“the life--Jesus, "the Word of life." was manifested--who had previously been "with the Father." show--Translate as in Jo1 1:3, "declare" (compare Jo1 1:5). Declare is the general term; write is the particular (Jo1 1:4). that eternal life--Greek, "the life which is eternal." As the Epistle begins, so it ends with "eternal life," which we shall ever enjoy with, and in, Him who is "the life eternal." which--Greek, "the which." the before-mentioned (Jo1 1:1) life which was with the Father "from the beginning" (compare Joh 1:1). This proves the distinctness of the First and Second Persons in the one Godhead.”
