Ephesians 6:10, “Finally, be strong in the Lord and his mighty power. 11 Put on the full armor of God so that you can take your stand against the devil’s schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world, and against the spiritual forces of evil in the heavenly realms.”
The main world war began in Genesis 3. Satan is angry with God Almighty for kicking him out of heaven. God’s Imago Dei and the whole earth is the battleground. Satan and his demons are smart enough not to attack God head-on, so he attacks His children. The problem with the 21st century church in America is not Satanic darkness; it is the lack of Christian light. The pulpits of America seeking to attract the lost and make them feel good about their “lostness” have dimmed the gospel light to a feel-good religion.
