To believe in the 6-day creation and the devolution of man attributes a failure in design by God. God is perfect. Why would he create the evil in the world.
No. There is no failure in design. The design allowed for infinite variety within the creation. It works as it’s supposed to.
The design was perfect, but no design, no matter how perfect initially nor how perfect the designer, can remain perfect once corruption enters into the mix.
Evil entered the world with sin. God did not create it. With the capacity for choosing good, comes the capacity to reject it and choose *not good*. That is what evil is.
“To believe in the 6-day creation and the devolution of man attributes a failure in design by God. God is perfect. Why would he create the evil in the world.”
I can’t really agree with this statement. First of all, what man can know fully the purposes of God when he set about to make His creation? Unless one is sure that the Lord has revealed all of his plans and purposes, then how can one attribute a failing to God based on any observation of the creation, without knowing His intent? Perhaps evil itself serves a purpose of which God is aware, but of which you are simply ignorant?
Second, regarding the creation of evil, I believe it’s altogether too simplistic to say that God created evil. I believe the best definition of evil is disobedience to the will of God. God cannot disobey His own will, therefore, God cannot, by that definition, commit evil. Only a creation of God, with the ability to choose obedience or disobedience, could originate evil. If you wish to ascribe to God responsibility for creating the ability to choose evil, then I think you would be able to make a more sensible argument.
