1 John 1:2

For the life was manifested - Was made manifest or visible unto us. He who was the life was made known to people by the incarnation. He appeared among people so that they could see him and hear him. Though originally with God, and dwelling with him, John 1:1, yet he came forth and appeared among people. Compare the Romans 1:3 note; 1 Timothy 3:16 note. He is the great source of all life, and he appeared on the earth, and we had an opportunity of seeing and knowing what he was.

And we have seen it - This repetition, or turning over the thought, is designed to express the idea with emphasis, and is much in the manner of John. See John 1:1. He is particularly desirous of impressing on them the thought that he had been a personal witness of what the Saviour was, having had every opportunity of knowing it from long and familiar contact with him.

And bear witness - We testify in regard to it. John was satisfied that his own character was known to be such that credit would be given to what he said. He felt that he was known to be a man of truth, and hence he never doubts that faith would be put in all his statements. See John 19:35; John 21:24; Revelation 1:2; 3 John 1:12.

And shew unto you that eternal life - That is, we declare unto you what that life was - what was the nature and rank of him who was the life, and how he appeared when on earth. He here attributes eternity to the Son of God - implying that he had always been with the Father.

Which was with the Father - Always before the manifestation on the earth. See John 1:1. “The word was with God.” This passage demonstrates the pre-existence of the Son of God, and proves that he was eternal. Before he was manifested on earth he had an existence to which the word life could be applied, and that was eternal. He is the Author of eternal life to us.

And was manifested unto us - In the flesh; as a man. He who was the life appeared unto people. The idea of John evidently is,

(1)That the Being here referred to was forever with God;

(2)That it was proper before the incarnation that the word life should be given to him as descriptive of his nature;

(3)That there was a manifestation of him who was thus called life, on earth; that he appeared among people; that he had a real existence here, and not a merely assumed appearance; and,

(4)That the true characteristics of this incarnate Being could be borne testimony to by those who had seen him, and who had been long with him. This second verse should be regarded as a parenthesis.
