And have no fellowship with the unfruitful works of darkness, but rather expose them.
God’s way is symbolized in the Bible as light, and darkness symbolizes sin and evil. Many times the apostle Paul encouraged faithful Christians to avoid the darkness of Satan’s lawless thinking and evil influences. For example, he wrote, “We do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places” (Ephesians 6:12).
He also wrote to the Corinthians: “For what fellowship has righteousness with lawlessness? And what communion has light with darkness? And what accord has Christ with Belial?” (2 Corinthians 6:14-15).
The custom of Halloween, derived from popular pagan festivities to appease evil spirits, is definitely a time of darkness.
Paul continues by quoting from Isaiah 52:11 , “Come out from among them and be separate, says the Lord. Do not touch what is unclean, and I will receive you” (2 Corinthians 6:17).
God’s people are to live no longer as the ungodly do in lewdness and greed ( Ephesians 4:17-19 ). How better to describe the risqué adult costume parties and the demands for treats of the younger crowd but as lewdness and greed?
