The flood ended, the year long journey was done. Imagine the uncertainty for Noah and his family, they had witnessed the destruction of all humans (except the eight in the ark) and animals, etc. on the face of the earth. What can be said in the aftermath of that? Noah can’t, so God speaks.
In 9:1-7 God reiterates the original command given to Adam and Eve in the Garden. “Be fruitful and multiply” (9:1, 1:26, 28). In other words, life changed, but God did not. He was setting back the clock so to speak. Sin had entered and ultimately led to the destruction of so many. But God is not finished. He sets in motion his plan for humanity, and ultimately for the perfect solution, sending his Son, Jesus Christ, to take all of God’s wrath against sin upon himself. “The one who believes and is baptized is saved.”
But God does more. He sets a rainbow in the sky as a reminder of God’s pledge not to destroy the earth through a flood. As Noah and all descendants see the rainbow, they can be reassured of God’s promises. But notice that the key is not that Noah and his descendants remember.
Your God Is Too Small —a book written by J. B. Phillips from back in the 1950’s. One reviewer on Amazon put it this way: “[God is] not a cosmic policeman or a divine grandfather. Neither is He a bellhop, a tottering old man, nor a fire-breathing despot.” Who is this God? Is my God too small?
Paul addresses that in his prayer in Ephesians 3. “Now to Him who is able to do far more abundantly beyond all that we ask or think…” The real challenge for us as Christians: do we believe that? Or do we pray and live as if “my God is too small”?
