Why do Reformed Christians emphasize grace?

Reformed theology places immense importance on grace as the unmerited favor that God extends to sinners. Ephesians 2:8-9 teaches that we are saved by grace through faith, not of ourselves; it is the gift of God. The parable illustrates this, showing how the publican, who acknowledged his sinfulness and need for mercy, left justified due to God's grace, not his own works. Grace emphasizes that salvation is entirely God's work, and human effort or merit play no role in securing it. This understanding fosters deep appreciation and gratitude among believers for God's sovereign grace in their lives.
