Father of lights
Rev 4:3 And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald.
There is a throne in heaven and one who sits upon the throne with absolute power. Atheists and humanists wish to believe that there is no throne, no absolute authority. The one on the throne John describes from his own heart. How can you describe spiritual things in a natural way? To look upon him was to look on beautiful colors of light, as to look at beautiful precious stones. A jasper, probably like a diamond, was sparkling clear white, representing purity and holiness. White contains all the colors, from him is all things of truth and beauty.
James 1:17 Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
A sardine stone is red, representing judgment and the blood of Christ. He is absolute judge and all things are purged by faith in the blood of Christ.
Around the throne was a rainbow; John describes it as an emerald, which is green. I see green as representing life, as in the garden of Eden.
Gen 1:11 And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.
Gen 1:12 And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good.
The rainbow represents God's covenant and mercy. It also is a reminder that God keeps his covenants and promises. We have His many promises to us in the Bible. These we should know and do. They are our treasure from heaven.
Purity, judgment, mercy, abundant life and God's promises are represented at the throne. The greatest promise I see is:
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
No flesh can see God, but John saw in the spirit. We shall see him in our spirit bodies, because of his promises. He is faithful and good; Loving and just. God should be honored and worshipped with all our heart.
