1:2 by his Son. God spoke intermittently and partially by the Old Testament prophets, but finally and fully by His Son, through the apostles (Hebrews 2:3).

1:2 heir of all things. See note on Romans 8:17; also see Psalm 2:8.

1:2 made the worlds. The Son is the Creator of all things (John 1:1-3; Ephesians 3:9; Colossians 1:16). Here the Scripture notes that Christ created the “space/time” cosmos. He is Creator of time as well as space, and all things. The Greek word aion, can be translated either “ages” (e.g., Ephesians 2:7) or “worlds” (e.g., Hebrews 11:3). It embraces the idea of time as well as space and matter, thus beautifully reflecting the scientific concept of the universe as a space/matter/time continuum.
