Genesis 9:15

I will remember my covenant. The rainbow, a natural physical phenomenon, was a fitting symbol of God’s promise never to destroy the earth again by a flood. Inasmuch as the climatic conditions of the earth would be completely different after the Flood, and rains would in most parts of the world take the place of the former beneficent dew to moisten the soil, something was needed to quiet men’s fears each time rain began to fall. The spiritual mind can see in natural phenomena God’s revelations of Himself (see Rom. 1:20). Thus the rainbow is evidence to the believer that the rain will bring blessing and not universal destruction.

John saw in vision a rainbow surrounding the throne of God (Rev. 4:3). Man looks on the bow to recall the promise of God, but God Himself looks upon it to remember and fulfill His promise. In the bow man’s faith and trust meet God’s faithfulness and immutability.

The beams of holy light streaming forth from the Sun of Righteousness (Mal. 4:2), as seen by the eye of faith through the prism of life’s experiences, reveal the beauty of the righteous character of Jesus Christ. The eternal covenant between Father and Son (Zech. 6:13) assures to every humble, faithful son and daughter of God the privilege of beholding in Jesus the One altogether lovely, and, beholding Him, of being changed into His very likeness.
