John was written during the end of the first century A.D. The Gospel was addressed to people living in Asia Minor that were struggling with many problems. Some writers think that the primary problem in Asia Minor during John's time was Gnosticism. John explains clearly why he wrote to them in John 20:30, 31. He wrote to them so that they may believe in Jesus Christ.
The class lectures will approach the Gospel of John on an exegetical platform. The class will go verse by verse. Time will not permit for the entire book to be approached that way, however. Therefore, please read some of the more advanced commentaries to receive quality understanding of Greek words and phrases as well as commentary and theology.
