BRIEF COMMENTARY ON THE LESSONS
Lesson 1: Genesis 1:1-2:4a (C); Genesis 1:1-2:3 (E, L)
This is the first of two creation accounts found in Genesis. God creates through the power of his word. This account suggests that God is not quite as close to his creation as does the account beginning in Genesis 2:4b and following, where God takes a hands--on approach to forming humankind out of clay. The word used for God's creative acts is bara and is used only in reference to the Lord. God creates from nothing; humans form things from that which already exists.
