Jehovah's Witnesses believe that Jesus is God's only direct creation, and that it was Jesus who created all other things:
Since all created things had a beginning, there was a time when God was alone. Countless ages ago, however, God became a Creator. Who was his first creation? The last book of the Bible identifies Jesus as “the beginning of the creation by God.” (Revelation 3:14) Jesus is “the firstborn of all creation.” That is so “because by means of him all other things were created in the heavens and upon the earth, the things visible and the things invisible.” (Colossians 1:15, 16) Yes, Jesus was the only one directly created by God himself. (Who Is Jesus Christ? on wol.jw.org)
We see this most clearly in the Jehovah's Witnesses translation of Colossians 1:15-16:
Colossians 1:15-16 (NWT) He is the image of the invisible God, the firstborn of all creation; because by means of him all other things were created in the heavens and on the earth, the things visible and the things invisible, whether they are thrones or lordships or governments or authorities. All other things have been created through him and for him.
But Isaiah 44:24 says that it was Jehovah who created all things by himself: note the last line of Isaiah 44:24 which says that no one else was with Jehovah, probably speaking primarily about humans, but also angels and other spiritual beings, which would seem to preclude God co-creating with Jesus.
Isaiah 44:24 (NWT): This is what Jehovah says, your Repurchaser,
Who formed you since you were in the womb:
“I am Jehovah, who made everything.
I stretched out the heavens by myself,
And I spread out the earth.
Who was with me?
How do the Jehovah's Witnesses reconcile Isaiah 44:24 with their belief that Jesus is the only direct creation of God and it was Jesus who created all other things?
