I have seen, and have testified that this is the Son of God."

 The Fourth Gospel begins and ends with life. At the very beginning we read that in Jesus was life; and at the very end we read that John's aim in writing the gospel was that men might "believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name" ( John 20:31). The word is continually on the lips of Jesus. It is his wistful regret that men will not come to him that they might have life ( John 5:40). It is his claim that he came that men might have life and that they might have it abundantly ( John 10:10). He claims that he gives men life and that they will never perish because no one will snatch them out of his hand ( John 10:28). He claims that he is the way, the truth and the life ( John 14:6). In the gospel the word "life" (zoe, G2222) occurs more than thirty-five times and the verb "to live" or "to have life" (zao, G2198) more than fifteen times. What then does John mean by "life"?
