The sermon concludes the exegesis of Romans 16 by examining Paul's warnings against false teachers and his benediction, which highlights the revelation of the mystery of the church. The speaker transitions to a systematic overview of the epistle, outlining its structure from condemnation to justification, sanctification, and glorification. This framework is used to distinguish the Protestant view of salvation, where justification is a past legal declaration, from the Roman Catholic view that treats it as a process. The teaching emphasizes that believers are simultaneously righteous and sinners, relying on faith for both justification and the ongoing process of sanctification. Finally, the sermon sets the stage for a deeper study of human depravity in Romans 1-3, contrasting Arminian and Calvinist perspectives to establish a biblically faithful understanding of God's grace.
