CTF 2025 - Session 2 - Divine Simplicity
Divine simplicity — the doctrine that God is without parts of any kind, physical or metaphysical — is the necessary precondition for God to be the absolute first cause of all things confessed in Romans 11:36. This lecture, drawn from 2LCF Chapter 2 Paragraph 1, works through the logic of composition and dependence to show that any being composed of parts is doubly dependent: upon those parts and upon whatever unifies them, and is therefore disqualified from being the uncreated Creator. Divine infinity is then treated as a corollary of simplicity: because God has no compositional structure of finitude, his being is actual, unbounded, and without lack, which is the only reliable ground for absolute trust and worship.
CTF 2025 - Session 4 – The Depth of God’s Eternal and Incomprehensible Nature
What does it mean for God to be eternal, and can finite creatures truly know an incomprehensible God? This conference session works through the classical doctrine of divine eternity — arguing from divine simplicity, immutability, and infinity that God's eternity is not endless temporal succession but the timeless, simultaneous, and perfect possession of boundless life — before turning to divine incomprehensibility, which is not a confession of ignorance but the recognition that the knowledge God has revealed of himself in nature and Scripture far surpasses the creature's capacity to measure or contain it. The session draws on Boethius, Augustine, Turretin, Charnock, Owen, and Bavinck to show that the two doctrines are inseparable, and closes with Solomon's prayer in 1 Kings 8 as a doxological meditation: if heaven itself cannot contain God, no created mind can comprehend him, and that inexhaustibility is the very ground of endless worship.
2LCF Chapter 2 - Of God and of the Holy Trinity, Part 2
What does it mean that God is one, infinite, simple, invisible, incorporeal, and without passions? This Sunday school session works through paragraph 1 of 2LCF Chapter 2, tracing the classical attributes — or perfections — of God through their biblical foundations and the theological vocabulary refined by the church across centuries. Divine simplicity, aseity, incomprehensibility, and impassibility are each examined with care, showing how these doctrines are not abstract curiosities but guard the God of Scripture from distortion and secure the stability of his love, justice, and grace toward his people. The session closes by connecting the doctrine of divine impassibility to the assurance of salvation: because God does not move from one state to another, his love for his people is always most.
2LCF Chapter 3 - Of God's Decree, Part II
God's decree, as confessed in 2LCF Chapter 3, encompasses both predestination unto life and the reprobation of the non-elect — a distinction the confession handles with care but which Scripture addresses with directness in passages such as Proverbs 16:4, Matthew 11:25-28, and Romans 9:17-23. The sermon distinguishes three theological frameworks integral to understanding the decree in salvation: the Pactum Salutis (the pre-temporal, intra-Trinitarian covenant of redemption), the Historia Salutis (the unfolding of redemption in space and time), and the Ordo Salutis (the application of redemptive benefit to the elect). God ordains not only the end — the salvation of a definite number — but also all the means, grounding the church's obligation to preach the gospel, make disciples, and pursue the lost. The doctrine, rightly received, produces praise, reverence, admiration, humility, diligence, and abundant consolation rather than either hyper-Calvinist passivity or Arminian nervousness.
2nd London Baptist Confession of Faith (1689) - Sunday School Study - August 29, 2021
What does it mean that God is 'without body, parts, or passions'? This study works through Chapter 2, Paragraph 1 of the Second London Baptist Confession of 1689, examining the perfections of God under three classical categories: divine incorporeality (God has no body), divine simplicity (God is not composed of parts), and divine impassability (God does not undergo emotional change). By grounding each doctrine in Scripture and the church's historic theological grammar — including the distinction between proper and improper predication, accommodation, and anthropomorphism — the exposition argues that God's transcendence over every creaturely category is not a cold abstraction but the very foundation of confident worship and unshakeable assurance for his people.
Exodus 9
Exodus 9 records the fifth, sixth, and seventh plagues against Egypt — the death of livestock, the plague of boils, and the devastating hailstorm — each demonstrating that the Lord alone is the living and true God over all forces of nature. The plagues are not natural phenomena but direct sovereign acts of God, exposed as such by their precise timing, their discriminating effect on Egypt but not Israel, and the collapse of Egypt's magicians before their own affliction. God's hardening of Pharaoh's heart is treated not as injustice but as a righteous judicial act against a persistently rebellious sinner, a point Paul draws on in Romans 9 by quoting Exodus 9:16. The distinction between those Egyptians in verse 20 who feared the word of the Lord and those in verse 21 who did not becomes a pointed call to heed the gospel: Christ is the believer's Goshen, the place of safe refuge under the new covenant.
