What is the Devil?
Devil is the translation of the Greek word διάβολος diabolos
Using Strong’s Concordance: Devil <1228> διάβολος diabolos (from <1225> διαβάλλω diaballo; accuse verb) adj; Translated in the King James Version: ‘devil’ 35 times, ‘false accuser’ 2 times, ‘slanderer’ 1 time
Meaning:
The idea that the ‘devil’ is a fallen angel who opposes God’s purpose is a slanderous falsehood. Angels obey God perfectly. See Psalms 103:20
The only thing in this world which is opposed to God is man himself. Mark 17:18-23
The term, "Devil" is always used metaphorically to signify the evil which comes from within man.
I hope you find this helpful.
God bless,
