At the center of God’s mission stands the cross. In John 12, Jesus reveals that his suffering, death, and exaltation are not a detour from God’s plan, but the very means by which God’s love and holiness meet. In this sermon, we see how the cross glorifies God, defeats Satan, judges sin, and draws the world to Jesus—calling us to see the cross not as tragedy, but as the centerpiece of God’s saving mission.
