The following post is from Pastor John Patterson's "Thought of the Day from God's Word," and is used with his permission. The emphasis on certain sentences are mine, because they stood out to me. After reading it, I have found myself dwelling on the questions he poses, especially the last one. I thought you might enjoy pondering it, too.
Have you ever considered why the gospels written? What was the intent of the human author? Why did he include the information he shared?
"But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through His name."
John wrote his gospel so that men and women might come to believe (trust, have faith in) Jesus the Messiah, who was none other that the Son of God, and that they might come to have life (eternal, spiritual, true, in essence the life which God always wanted them to have). This was John's purpose in writing his gospel (good news) and it is God's purpose for His Word.
