One Day When Sin Was As Red As Could Be

         Visible light occupies a slice of the electromagnetic spectrum. Waves are identified by wavelength (how far between crests) and frequency (how many waves per second). The longer the wavelength, the lower the frequency; the shorter the wavelength, the higher the frequency. It takes more energy to produce a shorter wavelength, since more waves must be produced each second.

A beam of white light contains a mixture of all visible wavelengths. A beam composed only of waves measuring 680 nanometers would appear red. Viewing an object that reflects only 680 nm radiation, through a filter that allows only 680 nm radiation to pass through, would appear the same as viewing a white object through that same filter. Red viewed through red appears the same as white.

“Though your sins are like scarlet, they shall be as white as snow; though they are red as crimson, they shall be like wool.” The (red) blood of Christ, shed for us on the cross, renders our scarlet sins as white as snow in God’s eyes. Praise the Lord!
