Is Jesus omnipotent?

Colossians 1:16-17 NWT

For by him all things were created in heaven and on earth, the things visible and the things invisible, whether they are thrones or lordships or governments or authorities. All things have been created through him and for him. Also, he is before all things, and by means of him all other things were made to exist.

By means of who were all things made to exist?
Hebrews 1:3 NWT

He is the reflection of God’s glory and the exact representation of his very being, and he sustains all things by the word of his power. And after he had made a purification for our sins, he sat down at the right hand of the Majesty on high.

If Jesus "sustains all things by the word of his power", is he "all-powerful"?
