What was the meaning of the first rainbow?

• A. A sign of a future drought
• B. It was God's promise that the world would never again be destroyed by a flood
• C. A sign of a new covenant with David
• D. A signal to rebuild the ark

Answer: (B)

The rainbow after the flood is a sign of God’s lasting promise. After the waters receded, God told Noah that He would never again destroy all life by a flood, and He set the rainbow in the clouds as a visible reminder of that covenant for all generations. This moment happens in Genesis 9, right as God establishes the post-flood relationship with Noah and his descendants—the rainbow stands as a lifelong pledge that the destructive flood will not happen again.

This helps you see why the other ideas don’t fit. A future drought isn’t tied to this sign, and there’s a separate storyline about a covenant with David that concerns the throne and the Messiah, not a rainbow. The rainbow isn’t a signal to rebuild the ark either; the ark was part of God’s plan before the flood ended, whereas the rainbow marks the promise after it. So the first rainbow reminds us of God’s mercy and commitment never to wipe out all life by flood again.
