From Mary Baker Eddy's "Science and Health with Key to the Scriptures" (p. 339), heading title: "Evil not produced by God"
"Since God is All, there is no room for His unlikeness. God, Spirit, alone created all, and called it good. Therefore evil, being contrary to good, is unreal, and cannot be the product of God. A sinner can receive no encouragement from the fact that Science demonstrates the unreality of evil, for the sinner would make a reality of sin, — would make that real which is unreal, and thus heap up “wrath against the day of wrath.” He is joining in a conspiracy against himself, — against his own awakening to the awful unreality by which he has been deceived. Only those, who repent of sin and forsake the unreal, can fully understand the unreality of evil."
