“God’s call to Abram contained a double promise: that He would bless Abram, and that He would make him a blessing. Both sides of the promise were related to God’s pledge to make of Abram’s seed a great nation (Gen. 12:2). God would make Abram’s name great by the fact that He would raise up a great people of his descendants. They would share the blessing that God gave to Abram, and Abram would be blessed by God’s blessing to them.
“Our understanding of blessing has faded with our awareness of the presence of God. Blessing is the pronouncing of God’s favor. It includes the gifts that God gives as the evidence of His love and favor, but blessing is more than what God gives. It is the bond of favor that joins God’s people with Him.”
