What is the difference between grace and works in salvation?

In salvation, grace and works represent two fundamentally different paths in understanding how we are reconciled to God. Grace is God's unmerited favor extended to sinful humanity, allowing us to be justified through faith in Christ alone, as seen in Titus 3:5-6. Works, on the other hand, refer to human actions or righteousness that individuals might believe can earn them favor with God. However, Paul clearly states in Galatians 2:21 that if righteousness could be attained through our works, then Christ's death would be in vain. This stark contrast emphasizes that salvation comes by grace alone and not by our efforts, ensuring that all glory goes to God.
