Through Abram's faith and family, God started to restore the blessing. God called Abram from a pagan world to start a new nation. His promises to Abram later became a covenant (chapter 15).
God's calling of Abram later helped convince the Israelites to leave Egypt and go to the land God promised to Abram. It also reminded the Babylonian exiles of their need to return to their own land (for example, Isaiah 51).
