Is there anything more beautiful than an early evening sunset or a brilliant blue sky? Have you ever wondered why clear skies are blue and sunsets are orange-red? The sky looks blue to us on a clear day because the molecules in the air (78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide and a small amount of water vapor) randomly scatter the higher frequency (shorter wavelength) blue light from sun light more than they scatter the lower frequency (longer wavelength) red light. Because of the this random scattering, some of the blue light reaches the earth’s surface where we see it. On the other hand, when we look towards the sun at sunset, our eyes see orange and red because the blue light has been scattered away from our direct line of site, leaving the orange-red light. The scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of light is called Rayleigh scattering, which is named after British physicist Lord Rayleigh (1842-1919).
As I was thinking about these interesting facts, I could not help but think about the promises of Scripture about the beauty to come. The Bible says, “No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love Him.” (1 Corinthians 2:9, NIV) How wonderful is the thought that man can’t even come close to imagining the beauty of God, or the New Jerusalem and Heaven and earth that are to come (see Revelation chapters 21 and 22).
The Bible says that there is something else that may be even lovelier than the natural beauty of the sun and sky, caring feet. The Scripture says, “For there is no difference between Jew and Gentile – the same Lord is Lord of all and richly blesses all who call on Him, for, ‘Everyone who calls on the name of the Lord will be saved.’ How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can they preach unless they are sent? As it is written, ‘How beautiful are the feet of those who bring good news!” (Romans 10:12-15, NIV) How lovely are our “spiritual” feet? Do our hearts ache for others to know Jesus? Are we willing to walk over coals and jump over obstacles so that others can experience the coming indescribable beauty? Lord Jesus please forgive me when I hide my “spiritual” feet. Please send me to deliver your message of forgiveness and love to a lost and hurting world around me that desperately needs to hear it.
