A RAINBOW IS A BEAUTIFUL PICTURE OF CHRIST. Jesus is called the light of the world. A rainbow has 3 primary colours, red, green and purple. RED SPEAKS OF THE BLOOD OF CHRIST - His sacrifice on the cross for me. Genesis 8:21 says "The intent of man's heart is evil from his youth;" Jesus paid the price for my sin. "The blood of Christ", the Bible says, "cleanses from all sin." Now that's good to know. Isaiah 1:18 puts it this way "Come now, and let us reason together," says the Lord, "though your sins are as scarlet, they will be as white as snow; though they are red like crimson, they will be like wool."
GREEN SPEAKS OF NEW LIFE after the storm. Genesis 8:11 (NASB95) says, "The dove came to him (Noah) toward evening, and behold, in her beak was a freshly picked olive leaf. So Noah knew that the water was abated from the earth." The olive leaf was a picture of new life after the storm. Jesus said "I came that you might have life and have it more abundantly" Whoever believes in Him will not perish but have eternal life.
PURPLE IS THE COLOUR OF KINGS. When Jesus was being tried, they mocked Him and dressed Him in purple. He is called King of kings and Lord of lords. Jesus knew what it was like to go through a storm. He is still my King of kings and my Lord of lords.
The Rainbow declares to me today and perhaps to you too, "If I have been through a storm, then God still has a future for me." In fact you can't have a rainbow, without having a storm or at least rain.
