Every serious student of the Bible desires to understand the text, discover the biblical principles, and apply the truths to his/her life. This commentary is designed to help students, pastors, and Bible teachers understand the gospel of John in a simple manner. Working from the popular New International Version (NIV), the author provides helpful commentary on the text verse by verse. This verse-by-verse commentary is different from others in two respects. First, it is brief, while some commentaries are unnecessarily wordy and verbose. Second, it is Pentecostal in outlook. This implies that we generally adhere to the doctrine of biblical inerrancy and adopt a literalist approach to the interpretation of the Bible. The fourth gospel has been called the gospel of belief. It is different from the other three gospels. John’s gospel is a profound witness to Christ as the Son of God. Yet it is easy to read-the reason new Christians are asked to begin reading the Bible by starting with John. John is the deepest gospel of all; it brings us closer to Jesus than any other. Those who study it reap great rewards.
