Is God invisible according to the Bible?

Yes, the Bible describes God as invisible. The triune God is Spirit and therefore invisible. The Son is the visible image of the invisible God, and by Him all things were created, both visible and invisible, including thrones, dominions, principalities, and powers.

Les explains that the triune God is Spirit and is therefore invisible. The Son, however, is the visible image of the invisible God. Les points out that by the Son all things were created that are in heaven and in earth, visible and invisible, including thrones, dominions, principalities, and powers. Even Satan himself is a created being, created by God the Son. Every power ever exercised was created by the Son. Not only did He create them, but they were created for Him and for His purposes. Les further notes that by Him all things consist, meaning they are held together. He illustrates this by asking why the universe does not explode in nuclear fission, answering that God the Son controls every particle by the power of His Word.

Who is the image of the invisible God in Colossians 1:15?

Colossians 1:15 identifies God the Son, Christ, as the image of the invisible God. He is the visible manifestation of the invisible Godhead and the firstborn of every creature. Scripture presents Him as pre-eternal in existence, just like God the Father and God the Spirit.
