The sun was shining as I was driving in to work this morning. But just a few miles away, a huge thunderstorm was brewing. The combination of sun and rain made for a nice reminder of God's faithfulness. A beautiful rainbow. When I got into the office, I thumbed through my Bible to Genesis 9 to read about the first rainbow that was placed in the sky by God. It was a sign of a covenant with Noah and the world that God would never again flood the earth like He did at the great flood. Here is what God says:
"'This is the sign of the covenant that I make between me and you and every living creature that is with you, for all future generations: I have set my bow in the cloud, and it shall be a sign of the covenant between me and the earth. When I bring clouds over the earth and the bow is seen in the clouds, I will remember my covenant that is between me and you and every living creature of all flesh. And the waters shall never again become a flood to destroy all flesh. When the bow is in the clouds, I will see it and remember the everlasting covenant between God and every living creature of all flesh that is on the earth.' God said to Noah, 'This is the sign of the covenant that I have established between me and all flesh that is on the earth.'" (Genesis 9:12-17)
I could well imagine that early on after the flood when a big storm came rolling through, there could have been some fear that the flood was going to happen again. But then they might look up in the sky and see a rainbow of God's promise. It has been thousands of years since that first rainbow and yet it still appears today as a reminder. A reminder that God is faithful to his promise.
