In Greek the word for "word" is logos. It is used in many places, but of special interest is how it is used of Jesus. In John 1:1 it says, "In the beginning was the Word and the Word was with God and the Word was God." The Word is divine and the word "became flesh and dwelt among us," (John 1:14). In other words, Jesus is the Word of God who represents God to us and us to God.
The term is also used to describe the Scriptures (Rom. 9:6; Heb. 4:12), Christ's teaching (Luke 5:1), and the gospel message (Acts 4:31).
