This exposition of the Westminster Confession of Faith explores the doctrines of God's eternal decree, predestination, and the immutability of God's decree. It argues that the number of the elect is fixed by God's sovereign will, independent of human effort, faith, or works, thereby ensuring that all glory belongs to God alone. The teaching emphasizes that salvation is a monergistic work of grace, where the elect are redeemed, effectually called, justified, and sanctified solely by the power of the Holy Spirit. By referencing passages such as John 17 and Ephesians 1, this episode defends the Reformed perspective that God's purpose stands unchangeable, closing the door to human boasting and affirming the security of those chosen in Christ.
