The very thing that the skeptic says disproves the existence of God (the existence of evil and suffering in the world) is actually a strong evidence that there must be a God. Here is how we might reason this to be the case:
1. Evil exists in the world.
2. Evil is a departure from the way things ought to be.
3. If there is a way things ought to be, there must be a designed plan (or designed standard) for the universe.
In his book, Handbook of Christian Apologetics, Peter Kreeft said, "the very fact of our outrage at evil is a clue that we are in touch with a standard of goodness by which we judge this world as defective, as falling drastically short of the mark” (p. 123).
4. There cannot be a designed plan for the universe without a designer of the universe.
5. Evil is mankind’s departure from this designer’s standard and that designer is God.
