AI generated Summary: Drawing on Luther, Melanchthon, and Brentius, this sermon explores the crucial distinction between Christ's atoning work *for* believers and the Holy Spirit's transformative work *within* them, emphasizing that neither should be separated. It argues against equating faith with a meritorious act or a work of human effort, instead asserting that justification comes solely through apprehending Christ by faith, receiving His imputed righteousness, and ultimately experiencing a renewal that follows, not precedes, acceptance before God. The sermon ultimately calls for a life of holiness, recognizing the Spirit's indwelling and empowering presence as essential for fulfilling God's purpose, while steadfastly maintaining that true peace and assurance arise from Christ alone.
