Now the LORD had said to Abram: "Get out of your country, From your family And from your father's house, To a land that I will show you.  2  I will make you a great nation; I will bless you And make your name great; And you shall be a blessing.  3  I will bless those who bless you, And I will curse him who curses you; And in you all the families of the earth shall be blessed."

—Genesis 12:1-3 

God’s call to Abram (later Abraham) is far more than a footnote in history.

It tells about God’s grace.  God did not call Abram because Abram was righteous, but because God is gracious.  Joshua 24:2 informs us that he was an idolater before being called.

It tells us of God’s insistence that His people be willing to leave everything behind to follow Him.  Didn’t Jesus say as much in Matthew 16:24-26?

It tells us that the called must follow God’s direction even when we do not know where He is leading.

It tells us that God will direct us and that we must follow.  Since God cannot be pleased except by faith (Hebrews 11:6), we must follow in faith, when we cannot see (Hebrews 11:1).

It tells us that God not only blesses His people, but He blesses others through them.  Salvation does not end with us, but continues when we proclaim Christ and the gospel to others who will in turn be saved (Matthew 28:18-20).

It tells us that Jesus is the ultimate fulfillment of God’s promised blessing.  Though some think the promises are ultimately about Israel, the Apostle Paul makes it crystal clear that the promises are to and through “the Seed, who is Christ” (Galatians 3:16).
