Why is it wrong to add works to grace for salvation?

When individuals insist on adding works to grace for salvation, they negate the very foundation of the gospel. Acts 15 reveals the early church’s struggle with the Judaizers who taught that one must be circumcised and follow the law to be saved. This teaching obscures the truth that salvation is a free gift from God, accomplished entirely through the blood of Christ. As Paul writes in Galatians 5:1, returning to a yoke of bondage by mixing works with grace nullifies the gospel and leads to spiritual ruin. True salvation rests solely on Christ's finished work, ensuring that all glory belongs to God alone.
