Question:
How do we have evil today if God is perfect? How did sin come about?

Answer:
God made us so that we could make choices. In Isaiah 45:7 we are told that God created evil, but the Hebrew word “RA” used in this verse means “calamity;” never sin.

God is supreme and He will have the top place! “The Lord hath made all things for Himself: yea, even the wicked for the day of evil” (Proverbs 16:4). Without the wicked opposing Him we wouldn’t know His great power.
In Genesis 3:6-19, Adam and Eve made a choice to sin. God didn’t force them to do this sin. The serpent had to have sin in him to even be able to tempt Eve. Sin is anything against God.
God could have made man without the capability to sin, but He didn’t. He could have made us like robots or puppets, but would He then get the satisfaction from us wanting to please Him? Is God really loving if we don’t have a choice? We can’t fault God for sin; man made the choice to sin.
