Jesus has many titles in scripture including The Word of God made flesh.
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
1 John 1:1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;
1 John 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
Revelation 19:13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
One title people use refer to Jesus is “the Living Word”.
There is nothing necessarily wrong with referring to Him using this title, Jesus is the Word made flesh and Jesus was, and is, and ever will be indeed alive.
However, this title is not one He has used in scripture to identify Himself. So, while referring to Jesus as the “Living Word” is not necessarily wrong, it would be unwise to build a doctrine off of that title if He has not used that as a title for Himself in scripture.
There is one related usage:
Hebrews 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
The context here is scripture, the written word of God. Here we see that the word of God is “quick”, meaning alive, life-giving, living.
