During Israel’s formation as a nation, the people gathered at Mount Sinai to receive the Law of Moses, which included instructions how to set up their first tabernacle. Craftsmen were working on beautiful garments of blue, purple, and scarlet cloth, interwoven with gold; these garments meant for the priesthood were touching on the entire color spectrum visible to the human eye: from purple (violet), blue, gold, all the way to red. Apparently, priesthood wore a coat of many colors!
We associate the color “red” most often with love; and red has the farthest reaching wavelength still visible to the human eye, about 650 nm. Incidentally, love always reaches out, so the color “red” suits the love-theme very well.
Radio waves are about 100 meters in length, extremely long, and completely invisible to the human eye; radio waves are able to reach around the world and far into space. So is God’s love – invisible but far-reaching. His innate being reaches out, day and night. His love is an ongoing flow overcoming short and long distances. God will always find a way to reach out to His creation. That’s just who He is.
Blue has the shortest wavelength visible to the human eye: The visible blue light has a wavelength of about 475 nm. Because the blue wavelengths are shorter in the visible spectrum, they are scattered more efficiently by the molecules in the atmosphere. This causes the sky to appear blue during the main part of the day, no matter which direction we look. Similarly, God is both near and everywhere; He is scattered throughout the entire universe – so much so that we have the opportunity to meet Him anywhere we go.
We have a God of many colors! God’s spectrum of His being is wide, from red, to blue, to invisible. He is able to tune into any wavelength and get in touch with all of His creation. That is why He understands our hearts so well. Even when we feel a million miles away from Heaven, God is still near. We might not feel Him, but He is closer to us than our best friend.
