In order to get a good grasp on the book of John, it is beneficial to find out who wrote the book, why they wrote it, and who they wrote it too. It is also important to know why they wrote it. I will answer these questions as we go through the book it self. I believe the best way to start a complete study of this book is to see why the author said he wrote it.
John 20:30-31
Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
If you desire a full explanation of the introduction to the gospel of John visit the following site and listen to the introduction messages from Galyn Wiemers. Excellent resources. If I was to write out this intro it would basically be quoting his entire message so go get it directly before we proceed further.
