The theme of John's gospel is "believe." The whole reason he wrote this book is so that people who read it will believe in Jesus (see John 20:31). But why should they believe? And even more applicable, why should we believe? After all, the events of the New Testament are over 2,000 years removed from us today. Jesus' confrontation with the religious leaders in John 5 tells us why we should believe. Like a skilled lawyer, Jesus calls upon four witnesses to testify to His claims and these four give the reasons for our believing in Jesus Christ.
