Some additional Scriptures to wrestle with include…
Isaiah 30:28, “His breath is like a rushing torrent, rising up to the neck. He shakes the nations in the sieve of destruction; he places in the jaws of the peoples a bit that leads them astray.”
Isaiah 63:17, “Why, Lord, do you make us wander from your ways and harden our hearts so we do not revere you? Return for the sake of your servants, the tribes that are your inheritance.”
Romans 11:32, “For God has bound everyone over to disobedience so that he may have mercy on them all.”
The expression ‘author of evil’ often misdirects our focus. When someone ‘authors’ something, then that something is their final purpose. Certainly, God is not the ‘author’ of evil, for evil is not his purpose. However, just as certainly he is actively Sovereign over all evil and even our particular sinful choices. So how are we to understand this? Instead, God is the ‘author’ of grace and evil is merely a necessary supporting actor to frame the demonstration of his main actor, that is grace in us, his people. It should also be noted that even though God is actively, finally, and totally sovereign over all things, including sin, he ordains evil only indirectly through Satan and the demons, and demonstrates grace directly through his own hand in our Savior Jesus Christ. Perhaps we could compare God to a skeet shooter. He is the one who says ‘pull’ and lets evil fly through Satan as we learn from the book of Job. However, his purpose is to personally and expertly shoot the skeet. Though in the midst of our sin and pain now, we may not see it, but the Scriptures promise that Christ will shoot every skeet, 21 for 21! Perfect score! Hope in Christ!
