About this sermon

This sermon explores the Reformed theological concept of the Covenant of Grace, arguing that there is a single, unified covenant of salvation that spans both the Old and New Testaments. By analyzing the Westminster Confession of Faith and key passages such as Luke 24 and Romans 4, the teaching distinguishes between the 'shadow' of the Old Testament administration and the 'substance' revealed in Christ. The central argument posits that while the means of administration differ—moving from types and sacrifices to the Word and sacraments—the requirement for salvation remains faith in Jesus Christ for both Old and New Testament believers. The sermon emphasizes that the death of Christ, the 'testator,' activates this covenant, fulfilling the promises made to figures like Abraham and extending the blessing of salvation to all nations through the simplicity and efficacy of the New Covenant.
