The Psalmist's Description of Depravity

Jim ButlerPsalm 14

Psalm 14 furnishes a comprehensive doctrine of total depravity, showing that man's rejection of God is not merely intellectual but ethical — a practical atheism that issues in universal corruption and abominable works. The psalmist's two-part structure moves from the description of the ungodly (vv. 1–3) to the deliverance of the godly (vv. 4–7), with Paul amplifying the same argument in Romans 1–3 by citing and structurally imitating the psalm. The only remedy for the corruption of the heart is not behavioral modification but the righteousness of Christ received through faith — the salvation that comes out of Zion — which gives believers both ground for evangelism and comfort in a sin-cursed world.

2LCF Chapter 8 - Of Christ the Mediator, Part 1

Cameron Porter

What does it mean to confess that Jesus Christ is very God and very man, and why does the precision of that confession matter for eternal life? This introductory session on 2LCF Chapter 8 surveys the doctrine of Christ the Mediator by establishing both the necessary posture and the interpretive rules required for sound Christology, then sets out seven reasons why the study of Christ stands at the center of all Christian theology. The session moves from the scope of Scripture as Christ-centered revelation, through the connection of eternal life to a right knowledge of Christ, to the comprehensiveness of all redemptive benefits being located in union with Him, calling the hearer to pursue a high Christology as the only safe and saving confession.

2LCF Chapter 2 - Of God and of the Holy Trinity

Cameron Porter

The doctrine of the Trinity is the capstone of the confession's treatment of God, asserting that the one divine and infinite being eternally exists as Father, Son, and Holy Spirit — three subsistences of one substance, power, and eternity, each possessing the whole divine essence undivided. This session works through six confessional affirmations: that Trinitarian monotheism excludes tritheism; that confessing one God in three persons is no contradiction; that the persons do not collectively comprise God in fractional parts; that the persons are distinguished solely by their eternal relations of origin; that Father, Son, and Holy Spirit are fully co-equal, co-eternal, and consubstantial; and that the doctrine of the Trinity is not a cold academic exercise but the very foundation of all communion with God and comfortable dependence on Him.

2LCF Chapter 2 - Of God and of the Holy Trinity, Part 1

Cameron PorterJohn 17:3

Eternal life consists in knowing the only true God and Jesus Christ whom he has sent (John 17:3), which means the knowledge of God is not optional for Christians but is the very substance of their salvation. This session opens a multi-week confession study of 2LCF Chapter 2 (Of God and of the Holy Trinity) by establishing what theology proper is — the study of the being, attributes, and works of the triune God — and why it is primary: it is grounded in God's creative purpose, commanded in Scripture, promised in the New Covenant (Jeremiah 31:31-34), and urgently needed in the face of false religion and bad theology. Six preliminary interpretive helps are then introduced to prepare the mind for rigorous and reverent engagement with the doctrine of God, including the necessity of recognising the ontological chasm between Creator and creature, God's revelatory condescension, and the joint propriety of affirmations and denials.

John's Incarnation Theology

Cameron PorterJohn 1:1

John 1:1–18 presents the most concentrated incarnation theology in the New Testament, and this sermon works through that prologue under four headings: the eternality of the Word, his personal distinction from the Father, his full and essential deity, and his true humanity. The Word who has always existed as God, distinct from the Father yet of one undivided substance with him, took to himself man's nature — not by casting off deity, nor by confusion of the two natures, but by a condescension in which he remained what he always was while becoming what he was not. The sermon guards each heading by naming and refuting the classical heresies that have distorted each truth, drawing on John 8, John 18, John 20, Philippians 2, and 1689 LBCF 8.2. The application calls believers to deepen their knowledge of this Christ and urges the unconverted to believe on the Lord Jesus Christ before that same Christ comes as the sovereign judge of Revelation 19.
