The words that accurately describe God’s choice to rescue humans from sin are gracious, loving, and merciful.
- Gracious reflects the idea that God's act of rescuing humanity is an unmerited gift.
- Loving emphasizes the relationship and care God has for humanity.
- Merciful highlights God's compassion and forgiveness towards those who have sinned.
The terms just and obligatory don't quite fit the context as they imply a requirement or a duty rather than a voluntary act of kindness or love. Unrighteous is contrary to the nature of God, as it refers to a lack of moral integrity.
