Why is mixing works with grace dangerous for Christians?

Mixing works with grace is dangerous, as the sermon explains, because it distorts the pure message of the gospel that Christ’s work alone is sufficient for salvation. In Romans 11:6, Paul makes it clear that if it is by grace, it is no longer based on works, otherwise grace would not be grace. This duality creates a false assurance, leading people to believe they can contribute to their salvation, which in reality, is solely a work of God. The people of Israel in Amos' time epitomized this danger by engaging in idolatry while claiming to worship God. The implication is serious: if one believes they can earn favor with God through works, they risk facing judgment without the righteous covering of Christ.
