The prism is usually a solid piece of clear glass in triangular form-that is, having one base and two sides. A ray of white light passing through such a prism is bent twice-once on entering and once on leaving the prism. The wave-lengths for each color being different, they are thus separated, so that each color embodied in the ray of white light is revealed to our eye. The same result is produced by the rays of the sun passing through the drops of rain, and the majestic "rainbow in the cloud" is produced. A complete rainbow spans the firmament from horizon to horizon-a beautiful symbol of the immutability of God's covenant with man and the whole earth that the waters of the flood shall never cover it again (Gen. 9:9-16).

Now if the rainbow's form is significant, we may surely look for the colors to be no less so.

Beginning with RED, we see in it humanity-man (Adam, means red earth), formed of the earth as Scripture tells us; and our blessed Lord has taken on humanity, to link it with Himself for ever.

Next to the Red in order we have the ORANGE, which, being a combination of red with yellow, to understand it we must first interpret the YELLOW. This, like the gold in Scripture, speaks to us of God in His divine glory. All the vessels of the Tabernacle were covered with gold. The beautiful sunsets also bear to us like witness. Therefore, in the Orange (red and yellow combined) we see "God manifest in the flesh," having come down from the glory and taken upon Himself the form of man. GREEN is nature's garb. It gives us that color of which the eye never tires. There is nothing of red in it, all comes from above-the yellow and the blue combined. It speaks of eternal life from the living, life-giving God, as imparted by BLUE, the Spirit from heaven. It was the Spirit by whom our Lord was conceived in the Virgin, and by the same "eternal Spirit He offered Himself without spot to God," and by the same Spirit Jesus "was raised from the dead." The combination of yellow and blue tells of life from above-the gift of God! Here "the flesh (red) profiteth nothing," but by grace it is raised up in the body of Christ and appears as INDIGO, the Man Christ Jesus at the right hand of God in heaven for us. " Flesh and bones, as ye see me have " is there, and there for us, as God's pledge of our glory. Then, when all the redeemed are with Him, God's purposes will have been accomplished, and then appears the VIOLET. The "sons of men, in whom are His delights," are at last seen with Him in a heavenly sphere, in heavenly character and glory, fitted to dwell with and commune with Him who is love, through Him who is light, in the Father's house for ever!
