“The LORD said, ‘Shall I hide from Abraham what I am about to do, seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?’” – Genesis 18:17-18
Abraham had a very special part to play in God’s plan to call the world’s tribes to himself. Abraham’s God given role in the Lord’s design for his elect warranted, by God’s reckoning, an equally special seat at the table for Abraham. God choose to lift up Abraham for a special purpose and thus, choose to include the Father of nations in his plans for Sodom’s destruction.
Abraham was not special because of anything in himself. He was a typical sinner, like every man before and after him. However, God’s chosen purpose for Abraham was great and a key component of God’s plan to reach the world with his perfect grace and mercy.
Through Abraham God will advance salvation for billions of men and women. God’s launch of the mission to reach the lost through Abraham gave our forefather a peek behind the curtain. Eugene Roop says, “Through Abraham’s chosenness God acts to promote life, not only for Abraham’s family but for all families. God’s soliloquy speaks of Abraham’s life-promoting role through the familiar promise language of this saga: ‘in him all the nations of the earth will be blessed.’” Abraham, as the instrument of God, was designated to usher in the calling of God’s elect to himself.
God viewed Abraham as special because he was part of God’s plan. Abraham’s descendants share equal part in the divine plan to reach the lost. Descended from Abraham, Isaac, and Jacob, modern Christian disciples have received God’s promise he will use us to bless the nations. As heirs of Abraham, we play preordained and extraordinary parts in God’s plan to create a great and mighty nation among the people of the earth.
The nations are to be blessed through the work of Christians for God’s glory. As we go out in missions, evangelize our neighbors, or preach the word, modern disciples of the Lord are fulfilling God’s covenant with Abraham.
