“Wash yourselves, make yourselves clean; Remove the evil of your deeds from My sight.
Cease to do evil, Learn to do good; Seek justice, Reprove the ruthless, Defend the orphan, Plead for the widow.”
— Isaiah 1:16:17 —
What is evil isn’t up to you or anyone else to determine. God has already declared what is evil and what it good, it’s up to you to learn which is which and then to obey Him by putting evil away from you forever.
Stop doing evil.
Learn good and do it!
Pretty self explanatory.
