Why is it dangerous to add works to faith in Christ?

When we add works to faith, we essentially claim that Christ's death was insufficient for our salvation, which contradicts the core message of grace. The Judaizers attempted to persuade Gentile believers that in addition to faith, they had to adhere to the Old Testament laws for salvation. This mindset still pervades many belief systems today, suggesting that our actions can contribute to our redemption. However, in Colossians 2:16-17, Paul clarifies that these laws are mere shadows of what is fulfilled in Christ. Trusting in anything beyond Jesus for salvation detracts from the faith we have in Him alone and confuses the gospel.
