This picture is an illustration about discernment. Viewed in daylight and under ultraviolet light it is somewhat difficult to see a clear distinction between the orange/red (things that are evil) and the white/aqua colours (things that are good according to God). Viewed in the dark, this is the world seen with God’s ‘clarity’. To God, there are no areas of grey- only that humans can lack discernment. Something is either good or evil with no in-between.
“For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.” (Hebrews 4:12, NIV)
