Have you seen a rainbow recently? After God send the flood to destroy the earth in the day of Noah, God said, "I will establish my covenant with you; neither shall all flesh be cut off any more by waters of a flood; neither shall there any more be a flood to destroy the earth." Then God gave Noah the rainbow as a token of the covenant agreement. The rainbow is also reminder of God's promise to us today.
Just before writing this counseling brief, I stepped outside my office to see a beautiful full rainbow. I had just been through an intensive emotional healing session with an individual. The rainbow reminded us not only that God would never again destroy the earth with a flood, but that God's Word is always good. His promise to heal emotional wounds today is just as good as the promise not to destroy the earth again with a flood. His promises to bring prosperity and physical healing are just as good as His promise to not to destroy the earth again with water.
In fact, Paul wrote in II Corinthians 1:20 "For all the promises of God in him are yea, and in him Amen, unto the glory of God by us." The word "yea" means "yes" and the word "amen" means "so let it be." If you are holding to a promise in the Word, you can also let the rainbow remind you of the faithfulness of God.
