The Bible contains the meanings of words, colors included telling us to compare spiritual with spiritual, not spiritual with the natural interpretation.
1 Corinthians 2:13 13 Which things also we speak, not in the words which man’s wisdom teaches, but which the Holy Ghost teaches,comparing spiritual things with spiritual.
The colors are in order, red, orange, yellow, green, blue, indigo and finally violet, or purple. They form naturally in the sky. It is a picture of the path to the Kingdom of God which is the Christian goal. God’s kingdom we pray:
Matthew 6:10 Thy kingdom come, Thy will be done in earth, as it is in heaven.
To enter the Kingdom you begin with red, which stands for the blood sacrifice, Jesus. No one comes into the presence of the Father without having recognized the blood covenant and its purposes.
Next is orange which is for deliverance from evil forces including demons and curses. A good bit of ignorance surrounds this in today’s churches leaving them to fight against evil without proper information and the results are sad.
After one has dealt with the devil you come to yellow which stands for holiness. Silver symbolizes redemption, and gold is holiness. It may seem superfluous to say this, but one can hardly expect to make any progress in the life of the Kingdom without having a genuine holiness. There is a form of Godliness which has no power. Pity.
2 Timothy 3:4-6 (KJV) 4 Traitors, heady, highminded, lovers of pleasures more than lovers of God; 5 Having a form of godliness, but denying the power thereof: from such turn away.
After yellow comes green meaning information, and growth. Many national companies use green for health, harvest, and information. Before you can have faith in God, which comes next, you need the Bible which contains the information you need.
Blue symbolizes faith. Without faith it is impossible to go on. Yes, everyone has a measure of faith which is provided to him/her but beyond this faith must be exercised at every single level if one wishes to progress in holy things.
Hebrews 11:6 But without faith it is impossible to please him: for he that comes to God must believe that he is, and that he is a rewarder of them that diligently seek him.
Romans 12:3 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.
I’ve heard Bible teachers and members of congregations say “I do not believe” this or that in the Bible and guess what? They don’t really, so move on. So there is not much reason to sit under their teaching. (Don’t confuse activity with progress. The devil can keep you busy for many years.)
After blue comes indigo. Some people call this lavender, or even shocking pink. It stands for spiritual warfare. Being a warrior for God comes after you have been through the previous processes, otherwise the devil tears your tail off. Spiritual Warfare brings a victory and after that comes the crown.
All ancient kings wore purple since purple dye was wildly expensive and only they could afford it. It comes from the crushing of a tiny little sea “worm” which produced the color. So now perhaps we can understand when the Palmist said, I am a worm and no man.
Psalm 22:6 But I am a worm, and no man; a reproach of men, and despised of the people.
Jesus was crushed for us all and now wears purple in heaven as King.
You will rule and reign with Christ here on earth if this process is yours. At this point the rainbow is a finished product. Your life has reached its goal.
