From the New Testament book of John:

1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
1:2 The same was in the beginning with God.
1:3 All things were made by him; and without him was not any thing made that was made.

1:10 He was in the world, and the world was made by him, and the world knew him not.

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.

1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
1:30 This is he of whom I said, After me cometh a man which is preferred before me: for he was before me.
1:31 And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water.
1:32 And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him.
1:33 And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.
1:34 And I saw, and bare record that this is the Son of God.

It is evident from what is said above that the "Word" is Jesus, the Son of God, and because "All things were made by him; and without him was not any thing made that was made"  we see that Jesus was the Creator.  Verse 1 also tells us that Jesus is God, and verse 10 tells us "the world was made by him".
