CTF 2026 - Session 3: Is God the Author of Sin?

Richard Barcellos

Two difficult theological questions frame this conference session: Is God the author of sin, and do a believer's sins work together for good? Drawing on 1689 LBCF 3.1, Acts 2:23, Acts 17:28, and Romans 8:28, the session argues that God's comprehensive, eternal decree encompasses all things — including sin — without making God personally culpable for evil, because sin is a privation of good rooted in the creature's deformed nature rather than in God's infinitely good being. The session closes by showing from Romans 8:28, with support from Robert Haldane and Genesis 50:20, that God's overruling providence turns even the believer's own sins toward their ultimate good and his glory — not as license to sin, but as ground for humility, dependence, and hope.
