Each of the four gospels is unique to one degree or another. Each one has a somewhat unique angle. Luke’s gospel tells the story of Jesus’ earthly ministry in letter form. It’s a rather long letter, as we’ll see in the introduction, but it is a letter nonetheless. His purpose for writing was to confirm to the man he was writing to those things the man had previously heard.
As we go through this book over the next several months, keep in mind that it was originally written to be a source of record to the person to whom it was addressed. As Christians, it is a source of record for us, too. The words we will read and study confirm what we have heard. They confirm what God has been saying to humanity since the Garden of Eden.
