Explanation

When God calls Abram, He promises not only to bless him but also that "all families of the earth" will be blessed through him. The promise is remarkable because its purpose reaches far beyond Abraham and his physical descendants. From the beginning, God's covenant with Abraham contains a universal dimension: blessing is ultimately intended to extend to the nations.

The New Testament explicitly connects this promise with the gospel. Galatians 3:8 describes God's words to Abraham as an advance announcement that the nations would be justified by faith, while Acts 3:25-26 applies the Abrahamic promise to the blessing brought through Christ. Jesus, a descendant of Abraham, becomes the means through whom God's saving blessing is offered to every people. This makes Genesis 12:3 an important stage in the developing messianic promise: the deliverer anticipated in Genesis will arise from Abraham's family, yet His mission will embrace the whole world.
