From the Confessing the Faith Conference 2026, this session introduces the doctrine of God's decree as treated in Chapter 3 of the 1689 Second London Baptist Confession of Faith. The lecture approaches divine decree as a revealed mystery — genuinely knowable through Scripture and providence, yet ultimately incomprehensible to creaturely minds — and sets the framework for subsequent sessions on predestination, divine authorship of sin, and the good purposes of God worked out even through human failure. Main points: - the nature of God's decree as a revealed mystery requiring special prudence - the limits and proper grounds of creaturely knowledge of the decree - an introduction to Chapter 3, paragraph 1 of the 2LCF Scripture references: - Job 26:14 - Romans 11:33-36
