“…[God] who is the blessed and only Potentate, the King of kings and Lord of lords, who alone has immortality, dwelling in unapproachable light, whom no man has seen or can see, to whom be honor and everlasting power. Amen.” 1 Timothy 6:15b-16.
The dictionary defines evil as, morally wrong; immoral; wicked. It could be something harmful or injurious; the synonyms though may be the best descriptions.
Depending on how it is used evil can be; sinful, iniquitous, depraved, base, vile, nefarious, pernicious, destructive, wickedness, unrighteousness, or corruption, to name a few.
“Then I saw another angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth – to every nation, tribe, tongue, and people – saying with a loud voice, ‘Fear God and give glory to Him, for the hour of His judgment has come; and worship Him who made heaven and earth, the sea and springs of water.’” Revelation 14:6-7.
