How does the Good Samaritan parable illustrate grace?

The parable of the Good Samaritan serves as a profound illustration of grace, where the Samaritan acts without regard for the societal prejudices that existed between Jews and Samaritans. Rather than asking what the wounded man could do to earn his help, the Samaritan offers assistance purely out of compassion, which reflects the unmerited favor that God extends to sinners. This act of grace not only provides physical healing but also signifies the mercy of Christ in seeking out the broken-hearted and offering them salvation without preconditions, aligning with the core message of the Gospel that salvation is not of works, but a gift of grace.
