John 3:4-10.

 Everyone who sins breaks the law; in fact, sin is lawlessness. ⁵ But you know that he appeared so that he might take away our sins. And in him is no sin. ⁶ No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.

EVIL is one of the ways we learn that we ourselves are a mystery; for we are not in full control of ourselves and cannot find any method of gaining control.  He shall deal out evil to the nations with a rod of iron when He comes again.

 Psalms 2:9
