The error of Synergism, which teaches that salvation is a cooperative effort between God and human works.

The sermon effectively uses personal anecdotes and biblical examples to challenge the congregation to examine the authenticity of their faith. However, the theological foundation is compromised by the explicit teaching of justification by works and the use of synergistic language, which undermines the doctrine of Sola Fide. While the intent to promote active faith is commendable, the method of articulation risks confusing the evidence of salvation with the cause of salvation.

Biblical Parallel (Archetype): Ephesus — The sermon maintains orthodox boundaries and does not cross into active heresy, but the explicit teaching of justification by works and the use of synergistic language regarding salvation indicate a compromised soteriology. The church archetype is Ephesus, reflecting a state of orthodox teaching that is incomplete or formal, lacking the full warmth of Gospel grace in its articulation of salvation.
