Synergism: The theological error that human works or rituals cooperate with divine grace to achieve salvation, rather than salvation being solely the work of God.

The sermon effectively utilizes compelling illustrations to highlight the sufficiency and accessibility of Christ. However, the theological foundation is compromised by a synergistic approach to salvation, where human faith and physical acts are presented as necessary conditions for receiving grace, rather than the result of it. This shifts the focus from God's sovereign initiative to human performance.

Biblical Parallel (Archetype): Pergamum — The sermon blends orthodox Christology with a synergistic soteriology that elevates human decision-making to the decisive factor in salvation. This blending of divine grace with human merit creates a theological compromise that obscures the sufficiency of Christ's work, characteristic of a church holding to truth but compromised by worldly philosophies of self-determination.
