StriderMTB of A Theology in Tension compiles a long list of Calvinist quotes about God determining evil. A Sample:
“So when I say that everything that exists — including evil — is ordained by an infinitely holy and all-wise God to make the glory of Christ shine more brightly, I mean that, one way or the other, God sees to it that all things serve to glorify his Son.”
“Plainly it was God’s will that sin should enter this world, otherwise it would not have entered, for nothing happens except what God has eternally decreed. Moreover, there was more than a simple permission, for God only permits things that fulfill his purpose.”
R.C. Sproul Jr.
God wills all things that come to pass…God desired for man to fall into sin. I am not accusing God of sinning; I am suggesting that God created sin.”
