You are correct as you are making the point that the authority and power of God is infinitely greater than any power of Satan and the 1/3 of the angels which followed him out of heaven.
But this power of God is only available to those who have placed their faith in the sacrifice of God’s Son alone, The Lamb that was slain to pay for the debt of our sin - Ephesians 2:8-9 For by [God’s] grace are you saved through faith, and that not of yourself, it is the gift of God, Not of works, lest any man should boast -
Romans 10:9 - That if thou shalt confess with thy mouth the Lord Jesus, and believe in thine heart that God raised Him from the dead, you shall be saved.
However, just a cursory look at the New Testament itself (remembering all scripture is God Breathed, and not inspired by human hands), reveals and expounds about a great spiritual war, which has impacted and will continue to impact men, society, and members of the church itself.
Even to believers, Paul writing to the Church of Ephesus in Ephesians 6, and to all believers in Christ, a warning and strategy for believers to utilize, or we would be casualties.
Just a cursory look brought up some powerful text on this subject of demonic and Satanic activity, including how it would increase as the time of Christ second coming gets closer. Some of the most important warnings of all were written to those believers which make up the body of the church and its leaders, and there would be demonic influence on and through some of those claiming to be teachers of Scripture in an attempt to mislead believers.
While a true believer does not need to fear Satan or his demons if we belong to God and we are living for Him, these influences are real and Christians are warned in scripture.
More than one warning even communicates how we can be deceived that Satan and his efforts, and the evil he wants us to commit is not something to be concerned with!
These few examples both prove the authority of God over Satan, and warn us.
I John 4:3-5
Mathew 4:1-11
Matthew 7:21-23
Matthew 8:28-34
Luke 9:1,37-42,51-55,
II Corinthians 11:13-15
Ephesians 6:12-13
I Timothy 4:1
I Peter 5:7-9
I John 4:1
Revelation 12:7-12
But those people have Free Will. We all have Free Will.
I wish, and pray, that people find Christ and raise their kids that way. And I do believe so many of our problems in Society relate or are a result of no Faith.
I just don’t believe or think it’s about spiritual demons. Evil people have always existed. They always will. I don’t think or believe books, movies, etc. are the cause of that evil.
There’s many people who have never been exposed to Christ, The Word, but I also don’t believe they are doomed to Hell for eternity due to the fact they were never exposed to The Word.
God wins the war.
