This question was originally asked on Randy's Facebook page.

I don't know of any way to give a good answer to this question in such a small space. But I believe that God is sovereign, and that He unfailingly accomplishes His purposes (Ephesians 1:10). Satan and humans have effectual choice that inflicts harm, yet God works everything together for the good of his children (Romans 8:28). Six chapters in If God is Good spell out in detail my positions:

God's sovereignty and Its Reach

“Free Will” and Meaningful Choice

This World’s Structure Is Necessary for Meaningful Choice

Meaningful Human Choice and Divine Sovereignty Working Together

Further Thoughts on God’s Sovereignty and Human Will

The God Who Brings Good Out of Bad
