God Is Sustainer.

He was before all things: He had a being before the world was made, before the beginning of time, and therefore from all eternity. Wisdom was with the Father, and possessed by him in the beginning of his ways, before his works of old, Proverbs 8:22. And in the beginning the Word was with God and was God, John 1:1. He not only had a being before he was born of the virgin, but he had a being before all time.

By him all things consist: They not only subsist in their beings, but consist in their order and dependences. He not only created them all at first, but it is by the word of his power that they are still upheld, Hebrews 1:3. The whole creation is kept together by the power of the Son of God, and made to consist in its proper frame. It is preserved from disbanding and running into confusion. - Matthew Henry
