What Kind of Objection?

[Speaking of Acts 4:27-28] “They gathered together to commit a heinous crime, but they only did what God’s hand and purpose had settled beforehand. We therefore see that God can control sinful actions without being defiled by those sinful actions. Of course, objections crowd into our minds, but they are not textual objections — at root they are philosophical objections. But the Bible says what it does” (The Paideia of God, p. 61).
