Right at the end of his Gospel, John tells us why he wrote it: that we may 'believe that Jesus is the Christ, the Son of God, and that by believing [we] may have life in his name'. John therefore filled his Gospel with carefully selected evidence to encourage our belief in Jesus. In this detailed yet easy-to-read commentary, Andrew Paterson examines the eyewitness evidence John provided concerning Christ's power and authority, showing us that John wanted this evidence to result not merely in intellectual assent to these truths, but rather in 'life' in Christ's name.
