But the people of Israel were fruitful and increased greatly; they multiplied and grew exceedingly strong, so that the land was filled with them. Exodus 1:7, ESVIn this short verse five phrases are piled together to scream to us about God's faithfulness. This people who came from infertile forefathers had a population explosion!!! And it was all just as God had promised. As Ligon Duncan points out, this verse borrows language from God's promises in the book of Genesis:
- Do not be afraid to go down to Egypt, for there I will make you into a great nation. Genesis 46:3, to Jacob
- I will multiply your offspring as the stars of heaven. Genesis 26:4, to Isaac
- I will make you exceedingly fruitful, and I will make you into nations, and kings shall come from you. Genesis 17:6, to Abraham
- And I will make of you a great nation… Genesis 12:2, to Abraham
- And you, be fruitful and multiply, increase greatly on the earth and multiply in it. Genesis 9:7, to Noah
- And God blessed them. And God said to them, “Be fruitful and multiply and fill the earth and subdue it.. Genesis 1:28, to Adam
In fact, God would conquer infertility again. After he multiplied the people of Israel, he sent his Son through their line. And Jesus, the promised Rescuer, was born of a virgin (Luke 1:31-37)!
Christ described our salvation as being “impossible with man,” but “possible with God” (Luke 18:26-27). God loves to create and allow impossible circumstances and situations and obstacles to rise up so that he can glorify his name when he does the impossible!
For consider your calling, brothers: not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth.  But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong;  God chose what is low and despised in the world, even things that are not, to bring to nothing things that are,  so that no human being might boast in the presence of God.  And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption,  so that, as it is written, “Let the one who boasts, boast in the Lord.” 1 Corinthians 1:26-31, ESVRejoice! God is faithful. He will do all that he has said, and no obstacle will be able to stand in his way. He will use unlikely people with seemingly insurmountable problems. And he will be glorified forever!
